Description

Cop automatic conveying device on the automatic winder

The present invention is relevant with thin network connection production high-quality yarn.During thin network connection is produced, first step production yarn, above-mentioned yarn winder of second step or rewinding, with reduce from outward appearance and powerful two aspects of machinery possible yarn defect and batch between irregular, thereby produce high-quality product.

The process velocity of winder or this process of rewinding is generally faster than spinning, and therefore a spot of winder ingot position promptly can be used for processing the yarn that a large amount of spinning spindle positions are produced.Produce a large amount of cops by spinning spindle position, these cops are by unwinding and be wound on again and have on a small quantity than on the much bigger bobbin of cop size.

The difference of this two procedures productivity ratio is so big, so that same bobbin winder can be used for processing simultaneously the yarn that the many fine spining machines of quantity are produced, and the yarn of the different yarn numbers of producing with fine spining machine not even.

Now the working ability of winding procedure generally all is installed on the spinning process limit, causes spreading unchecked of these products when avoiding product that bobbin winder processing fine spining machine comes out.

What loading and unloading were had requirement is not only the cop and the empty spool of full packages, also have a large amount of abnormal cops can't find out by the device that is installed on the winder ingot position because of loose thread corresponding on the spool as the cop of full packages not and those, winder ingot position can't be found out a class cop of additional loose thread again.After unloading, the abnormal cop of this class heavily delivers on the cop loose thread preparation device, so that deliver to bobbin winder processing after handling again, the whole yarns in intact spool.Through the such processing cop that still can not find loose thread once, unload the back and discharge, carry out separating treatment.

For winding procedure, the cop that spinning process should be produced is prepared once more, makes the loose thread of each cop be in the precalculated position, and usually, above-mentioned loose thread all hangs on the last hole of spool.On this spool, reel for yarn around and form cop.The automatic winding unit can grasp above-mentioned loose thread from cop automatically, begins winder after the feeding like this, has so continued the production of winder.

Have a large amount of materials to carry between fine spining machine and bobbin winder, empty spool will return fine spining machine, and these spools are again around last new cop.The full packages cop of producing on the fine spining machine will be delivered on the bobbin winder after preparing.In order to illustrate, but generally be per hour 30 cops even more of processed of each winder ingot position by the bobbin winder of at present up-to-date conceptual design.All the conveying of cop per hour will reach thousands of pipes.Such transportation work is very burdensome.The go-go equipment that may adopt in present institute is automatics, and the operative employee only plays the effect of inspection and troubleshoot.

In traditional bobbin winder, the conveying of cop and spool is to adopt the little railway carriage that has wheel, and cop and spool or employing handler are taken out from little railway carriage, or take out with hand simply.In more modern method, the conveying of cop adopts the method for conveyer belt as the patent according to No. 4571931 Schlafhorst of U.S. Patent No., and in this patent, cop is loaded onto the back and put down towards winder ingot position.At U.S. No.5, cop has the device that moves pocket to mobile employing of winder unit in the patent of 289, No. 674 Savio, always keeps its fully loaded and circulation, the cop reserves of getting ready with foundation.

The different technologies solution that another kind of cop is carried is the supporting vehicle that a pin is arranged in the middle of adopting, even in cop unwinding process, cop still remains on this carrier.This JP-A-49-12128 patent or Germany that has Japan to belong to Kanebo on the one hand belongs to 3,213,253 of Maurata; 3,29,583 and 3,235, No. 442 patents.This invention does not contact them when making actual fed with the processing cop becomes possibility, only need act on these supporters.Carrier is generally disc (as the plate of circle).When handling the yarn of a large amount of different lot numbers simultaneously, the model of cop can adopt instrument to determine, promptly determines from the different carrier of these cops.

According to prior art, the carrier carrying method of cop is generally realized by the mobile surface that they are stopped, and that is to say, adopts the mode of conveyer belt during rectilinear motion, is the mode that adopts rotating disc at circular motion.The processing method of this cop has some defectives, has suitable complexity as its transmission and conveying parts, and the staple fibre and the dust that are distributed by yarn produce a large amount of flyings, and these flyings can cause that parts damage or produce fault.Carrier is placed directly in that this fact means that any motion is undesired on the conveyer belt, may cause the carrier overturning, the danger that cop drops out.

Device involved in the present invention is to be used for cop is transported to automatic winder, method cop by carrier carries out processing on bobbin winder, and consider that cop is transported to the processing in winder ingot position of winder ingot position and cop, promptly in their spare space, what bobbin unwinding position and empty spool were discharged moves.

The purpose of this invention is to provide improved device, be used for carrying and handle, and make it to avoid the deficiency that shown with the prior art similar device by disc-supported cop of carrying and spool.

Carry on the bobbin winder of the present invention and the characteristics of loading and unloading cop and spool method and advance will be from exemplary explanation and embodiment and more obvious.Referring to accompanying drawing 1-4, they are:

Fig. 1 is the plane of induction system and bobbin winder, and Figure 1A has shown the method that transmits the carrier of cop in detail for front view.Referring to BB, can see that the cop carrier is supporting a full packages cop and towards the motion of direction, and the cop carrier is supporting empty spool and is moving in the opposite direction.Two interchannel fender rods have also been described simultaneously.

Fig. 2 and Fig. 2 A are total diagrams of induction system and running part thereof.Before dash area is the machine of bobbin winder corresponding to induction system;

Fig. 3 is the diagram of winder unit and its critical piece.

Fig. 4 is the plane of induction system and winder ingot position, the conversion embodiment of the discharge system of expression empty spool.

Cop carrier (1) as among Figure 1A in detail shown in, be by base (2), and the cop fulcrum post of being made up of ring (3) pin (4) etc. is formed, spool in the cop that is transported rests the last pin of ring (3) and is inserted on the bottom outlet of spool on the cop (5), the ring (3) diameter in the nature of things than spool slightly larger in diameter some, the diameter of pin (4) is more smaller than the underfill aperture of spool (5), has limited the upright position of spool on pin like this.According to the present invention, be used for supporting cop, and the carrier that transports them adopts some materials to make, these materials and the base angle of making at last can guarantee on the plane of described base and its stop, show less adhesion strength, when it is subjected to very little power, can on described plane, slide like this.

When carrying the action beginning, will be placed on the cop supporting disk by the known devices of cop employing own and the method for unwinding.

According to the present invention, behind the machine of bobbin winder, transport is installed, this device is used to carry whole cops that will feed all winder ingot positions of composition bobbin winder.

Described device is made up of running part (10), and available belt pulley of running part (10) or sprocket wheel realize, and along the moving by the passage between the two vertical axis guiding/drive disk assemblies (11) of level sealing, as circulation path.When running part (10) was made up of flat belt or cog belt, parts (11) can be common belt pulleys, and when running part (10) was made up of cog belt or chain, its drive disk assembly (11) was a sprocket wheel on the contrary.This two drive disk assembly one of them by drive motor (12) transmission, this class drives as has the motor of suitable reduction gearing.

At the running part that moves along the black arrow direction (10) promotion part (3) is housed, this promotion part is installed on the horizontal plane of cop carrier base (2), and the promotion carrier advances along said direction.Promoting part (13) can be formed and be rigidly attached on the belt (10) by carriage, and rectangular standing shape as shown in Figure 1.

Like this, cop carrier (1) is through the effect of side rotatable parts (10) and go in ring, stop or sliding on bearing-surface (14), owing to promote the impetus of part (13) and the effect of a pair of guide (15), make the cop carrier only can on the restriction track, carry out horizontal movement, as shown in Figure 2.

At said track left-hand side, have a system be used for be equipped with the full packages cop the cop carrier install to the free position of induction system, as shown.

Bearing-surface (14) is the same with the base plane of cop carrier base, has also adopted some materials to make, and makes its fine finishining degree guarantee that its adhesion strength to the supporting disk that supported is less, only needs very little strength that supporting disk is slided.

For the purpose of clearer, guide in Fig. 2 (15) has only shown that a part is so that make bearing-surface high-visible.According to the present invention, guide (15) is to install like this: it is installed in the top of carrier base, and is more bigger than the thickness of carrier base, and with bearing-surface certain distance is arranged.This bearing-surface is more bigger than carrier base thickness, is slightly larger than the diameter of ring (3) at cross one another that segment distance.

Its inboard of track that each winder ingot position on bobbin winder, guide are formed is towards said winder ingot position, the steering gear that this track has a fork (16) and is made up of bar or blade (17).This steering gear stops cop carrier passage accepting the extended conduct obstruction in instruction back, rather than pusher (13), along bearing-surface (14), by the steering gear of being instructed,, satisfy the requirement that the winder unit of putting on the shelf send cop with unillustrated traditional driving type in scheming.

Because the thrust that promotion carriage (13) moves right continuously and the resistance acting in conjunction of blade (17), the cop carrier is pushed to the circular arc passage of blade (17) bottom of the direction of winder ingot position, left the thrust of pusher (13) up to it, along the beeline channel arrival cop spare space, inside of winder ingot position.

When new cop arrives spare space (A), there is the sensing element of not representing among the figure to send signal command steering blade (17) and is returned to its stop position.

The rectilinear orbit that is used for the cop processing of inside, winder ingot position and the loop turn that cop is carried are similar, have bearing-surface (18), fixed guide device (19) and pushing mechanism.It has minimum three operating positions.First position, promptly so-called " (A) position " is the position that arrives from the cop that the cop induction system has just been sent here, this cop is here waited for and is sent to unwinding.Second position is that the unwinding position also is " (D) position ".Cop that can not unwinding promptly do not have the spool of yarn and further the cop of unwinding be sent to " (S) position " and be displaced into the induction system that is used to handle empty spool to unload.

In the diagram of Fig. 1 in order to simplify, many have only been represented one of in the winder ingot bit port, in fact the upper channel that is used to feed ready cop is to interconnect by the way with the lower channel that is used to discharge empty spool, and the winder ingot bit quantity of its quantity and bobbin winder as many.

It among Fig. 3 the diagram of winder ingot position critical piece.

Reference number (30) is for getting the cop of state ready, and its loose thread (31) is positioned on the top-portion apertures of spool.(32) expression is just at the cop of unwinding.Reference number (33) is the suction inlet of cop loose thread, loose thread is guided on the suction inlet of knotting device at this suction inlet of its position (33A), and in the position (33B), this suction inlet is drawn the loose thread on the cop (32).(34) sensor that then whether exists for the inspection yarn.The tensioner of yarn is shown in (35).Reference number (36) is positioned at the position (36A) of cop end to be delivered to loose thread on the knotting device (37) at this suction inlet on this position for the loose thread suction inlet of knotting device, and it siphons away loose thread with suction inlet (33) at its position (36B).Yarn clearer represents that with (38) (39) are to be used for the suction nozzle that bobbin (40) is gone up loose thread, and at its position (39A), its grasps the loose thread on bobbin, goes up at (39B) this loose thread is delivered on the knotter (37), and the bobbin driving roller is represented with (41).Bobbin transports arm and represents with (42).Track (43) is the predominating path of cop to yarn between the bobbin.

Cop (A) (D) or (S) instruction of sending of the motion between the position by winder ingot position decide.Yarn on cop has not had and has caused the time-out of winder, be positioned at the locational cop of unwinding (32) and be considered to yarn on it by winder parts unwinding light, this may be the complete unwinding of yarn, also may be to seek, grasp and the knotting baulk through the loose thread of certain number of times, the robot cell of bobbin winder order be at this moment changed by the cop of unwinding.

Subsequently, the transformation directive of unwinding cop is combined by main control unit, and it comprises that (A) calls new standby cop from the spare space, and it is freely and the instruction of shifting out empty spool to this cop when the cop conversion.The instruction of the new cop of need is moved upward by steering blade and realizes.(S) empty spool of position should shift out to vacate the position at once, and this shifts out action is what to begin to carry out at first signal of vacateing movable passageway.

According to the present invention, the inside cop motion of winder ingot position adopts the action that promotes to realize.

Describe in detail as Fig. 1, its action is carried out by pair of push rods (50) (51), and its fulcrum centers on pin joint (52) (53) also with connecting rod (54) interlock.They are positioned at guide (19) top, be subjected to importing bobbin winder compressed air to two-way function cylinder (55) effect after, can carry out along inserting needle respectively or be rotated counterclockwise.Show as implementing illustration in detail, the minimum consideration handle of bar (50) (51) bar (51) one its far-ends and pin joint (52) (53) are hinged respectively, when they push away downwards, promptly when shifting out channel direction and push away, bar is towards counterclockwise motion, the hinge place of its head end is rigidity, promotes to have on Fig. 1 plane the ring on the carrier of cop.These hinged places are folded state again when they return inactive state.Be subjected to having the carrying of wanting the unwinding cop when bar clockwise rotates, the obstruction of the ring on the dish also may be subjected to the obstruction of the new cop in spare space.Hinge point owing to be subjected to the spring action of traditional form unlisted on the figure, is got back to the state that their stretch again after removing all obstructions.

Bar (50) (51) moves in the counterclockwise direction and has arrived (50 ') (51 '), has run among the figure and has used (A) and (D) locative two pipe cops respectively, and they have been shifted onto (D) respectively and (S) on the position.Arrive the identical method in (D) position with (A) position cop, after new cop arrived (D) position, unillustrated sensor just sent and changes signal to main control unit on the figure, and this unit can send instruction subsequently and restart the winder program.

When the spool that shifts out arrives (S) position, just be discharged from once.Shown in Figure 1, the system that is used to carry empty spool is the same with the device that cop is sent into winder ingot position.It is by bearing-surface (14 '), and guide (15 ') and promotion part (13 ') are formed and be similar with above-mentioned parts.Such system is installed in the front side of bobbin winder, and is relative across bobbin winder with the system that handles cop, and is used to carry the empty spool of a large amount of winder ingots position discharge of forming bobbin winder.Empty spool is to the operation of transporting of induction system, by the robot cell's of bobbin winder instruction, and is subjected to the restriction of conventional version sensor (60).This sensor is a dibit optical pickocff, and along with the alarm that suitably shifts to an earlier date, it sends one and is provided with the signal that cop carrier carriage arrives.Shift action adopts catch bar system as hereinbefore to finish.This system is made up of catch bar (61), and it is around pin joint (62) rotation, and it is subjected to two-way cylinder (63) effect and carries out limited clockwise or motion counterclockwise.Behind the position that it can be grasped at by forthcoming carriage (13 ') when the cop carrier arrival that has empty spool, bar (61) is return its resting position at once.

Fig. 4 discharges another embodiment of empty spool system for bobbin winder.It has adopted at the carrying method of bobbin winder installed in front conveyer belt and has handled a large amount of empty spools that discharge a large amount of winder ingot positions on the bobbin winder.

According to technical solution as described herein, used its width of conveyer belt (70) slightly to surpass the cross dimensions of cop carrier, bar (51) is shifted the position of (51 ') onto, the cop carrier that has empty spool at least major part shift onto on the conveyer belt (70).On (S) position, both sides guide (19) adopts towards the wide banded structure of Way out, so the empty spool passing away is one to have the smooth circular arc of guide (15 '), does not have the danger of any obstruction.

The system of Fig. 4 also can adopt narrower conveying to bring realization, and in this case, the system that empty spool is pushed to conveyer belt has used additional thrust unit, bar as shown in Figure 1 (61), and it will have the cop carrier of empty spool and shift onto on the conveyer belt.

Cop induction system described herein provides many noticeable advantages than known system in the past, in these advantages, is that some are worth putting forward below:

But the feeding annular flow path continuous motion of full packages cop, and have all or great majority and prepare the unwinding cop, be kept in motion, to satisfy of the requirement of winder ingot position fast, to have formed simultaneously standby (storage) cop that is used for demand peak to cop.

Cop on the annular flow path keeps certain distance mutually, can avoid the crowded and collision in the course of conveying, and such closed-loop works and only adopts single transmission system to keep motion.Yet the conveyer belt in the past needs guide and transmission mechanism to change when changing the direction of motion.The existence of last guide (15) has guaranteed that the cop carrier stops on bearing-surface, cop always stands upright on vertical position, also always keep such state when movement velocity or direction change, so the transporting velocity of cop does not have restriction in essence.Flyings and the foreign material of removing inner accumulation can be opened in the non-unwinding stage in bearing-surface (14) and (18).
