The self-acting mule (10) consists of at least two sections of machine, respectively left (11) and right (12), independent from each other from the mechanical point of view, and each comprising at least a relative spool-bearing carriage (19a, 19b), relative spindles (14), relative cylinders (21a, 21b), relative fallers (24a, 24b), relative counter-fallers (26a, 26b), and relative drums for unwinding the spools (23a, 23b).
Description
Technical field
The present invention relates generally to a kind of self-acting mule of producing yarn, especially for the self-acting mule of producing the quality yarns in woven and the knitwear.
Background technology
The self-acting mule of known type in order to enhance productivity, needs some automation equipment to be used for loading the product (yarn) of wanting product processed (rove) and unloading to finish.Although these devices are expensive, make that production of machinery efficient is higher and reduce downtime.In order to keep the characteristic of processing and yarn as far as possible consistently, common trend is to load to self-acting mule to have the doff that obtains from identical combing line (classification).Therefore, self-acting mule is aimed at a classification of carding machine usually.In order to produce, self-acting mule of today needs the electric energy of about 100kW, and absorption peak is up to 140% of related power, and average consumption simultaneously remains on about 50%.Because its inherent structure, this machine has the feature of the intermittent duty of frequent acceleration and deceleration.
The self-acting mule of known type is by a plurality of motor operations now, and by managing and guaranteeing to process conforming electronic control unit and control as a main body.
The system that moves this machine comprises the element of following necessity:
-carriage motor.This carriage extends the rove that will process in the process of operating procedure, and can recover yarn in closing step on spindle;
-spindle motor.This spindle applies in the process of operating procedure and reverses, and in the process in closing step yarn is wound on the bobbin;
-send motor to.It in the process of operating procedure according to haulage be set in apply reverse in (solving) with single-motor provide rove to send to.In this case, move by the movable machinery ground guide roller of cylinder;
-cylinder motor and drum motor.In the process of operating procedure, being set in to apply (to solve with two motors) when reversing to rove according to traction provides suitably synchronous sending to.
-La yarn faller motor.Closing in the step of self-acting mule, yarn is being wound in the process of (winder) on the spindle, they regulate the winding tension of the tightness degree that is related to bobbin;
-faller motor.Closing in the step of self-acting mule, in the process of winder, they are according to the regular locating yarn about the spindle geometry.
In order to obtain above-mentioned motion, use a plurality of motors, its quantity can not wait to maximum 8 from minimum 5 according to the quantity of spindle on the self-acting mule.Solution with 7 typically uses maximum.
Traditional self-acting mule, example for example shown in Figure 1 generally includes single structure, comprises central module and two parts, is respectively a left side and right half, and described left and right part is divided from central division in the mode of substantial symmetry and is extended.Spindle quantity less than 600 machine in, core is holding following motor or actuator:
-the first motor by reference number 100 expressions, is used for the bobbin Support bracket;
-the second motor 101 is used for feed cylinder;
-Di three motors 102 are used for the cylinder of unwinding rove;
-Di four motors 103, the control spindle;
-Di five motors 104, mobile bobbin faller; And
-Di six motors 105, mobile conduct be used for the tensioning bobbin thread element draw the yarn faller.
For machine with greater number spindle, also provide two pairs of corresponding motors to replace fallers and draw the motor 104 and 105 of yarn faller, the position is the central authorities of part about corresponding basically.
All these motors conducts are mobile self-acting mule integratedly, and sends instruction by single controller 106, and described controller little by little transmits motion track and gives described spinning machine, thereby guarantees constant processing.
By using motor available on the market and/or actuator just can obtain all these motions usually.In fact, as required, DC, brushless and asynchronous motor all can use, and also can use air rammer.
The working cycles of self-acting mule makes machine fully be written into bobbin and guides rove subsequently to corresponding spindle.The time T of this action need and the quantity of spindle are proportional, and machine is not produced in this time course.
After finishing preparation, self-acting mule starts, the beginning production cycle.Each run and close and all spin out some yarns and collect on the spindle, this depends on the length of stretching.With yam count and material type in the closely-related time, spindle finishes after the operation of specific quantity.Repeatedly shutdown occurs because yarn disconnects in the course of the work, and in machine run, can't tie a knot again.Now, each machine stops owing to yarn disconnects, and all can relate to all spindles.
From viewpoint of energy, the axle of wasting most is a spindle axis, has used the motor of about 100kW rated power to make these spindles quicken and deceleration here.In these steps, the energy of acquisition equals about 140% of rated power.
It is necessary carrying out two or three doffs from the carding machine terminal part, and described terminal part is called as distributor, is used to be written into self-acting mule.Thereby the end that must handle each batch makes cotton mill be written into the carded bobbin of identical size, thereby makes waste minimum.Be difficult to control this operation for small lot batch manufacture.Can once be written into and process a doff, thereby solve the problem of handling each batch end.Because above-mentioned, obviously there is intrinsic restriction in traditional self-acting mule in flexibility, and is proportional with the spindle of greater number on the machine, production and the energy that uses also can be bigger.
Summary of the invention
The objective of the invention is to improve the performance of traditional self-acting mule, make that described self-acting mule has more flexibility and production efficiency is higher, and reduce downtime.
According to the present invention, described self-acting mule comprises at least two machine parts, and described two parts have the spindle of identical or different quantity, be respectively the right with the left side, see that from the viewpoint of machinery they are completely independent from one another.
When we mention the independent sector of machine, preferable quantity be two but and infinite; In fact, the independent sector of machine also can be three, four or more, has the described identical feature in back with reference to preferred embodiment.
According to the present invention, in traditional self-acting mule, the axle of movable support bracket, spindle, cylinder and cylinder is divided into two parts at least, and is independently of one another, and leans on its motor motion in every side of machine.Like this, each motor can change the size of power pro rata with spindle quantity.
In preferential solution, faller and draw the yarn faller to have their motor, described motor is arranged in the central authorities of each unitary part substantially.
According to the self-acting mule with two independent sectors of the present invention, in a preferred embodiment, use:
-two motors, the rated power of each motor are lower than the employed motor of traditional self-acting mule, are used to handle spindle: first motor is used for left half and second motor is used for right half;
-two motors, the rated power of each motor are lower than the employed motor of traditional self-acting mule, are used to handle two parts of bobbin Support bracket;
-two motors, the rated power of each motor are lower than the employed motor of traditional self-acting mule, are used to handle left and right sides cylinder and cylinder.
According to a kind of variation, use two motors to handle cylinders, handle the left side respectively with the right, and two motors are handled the left side and cylinder the right.
According to the present invention, also single control module can be arranged, the function of its management and at least two separate units of coordination, perhaps, according to a kind of variation, each several part has all been equipped its automatic control unit.
Like this, no longer be made of the single part of individual operation according to self-acting mule of the present invention, but become a kind of machine with at least two parts, two parts fully separately and independently of one another.
When shared identical control module of two independent sectors and identical electrical control panel, the saving that is obtained is quite big.In this case, the power separate management of the power of right half and left half in electrical control panel, and rely on and to be suitable for they are controlled as the software that two distinct entities manage, abide by at present effectively safety standard simultaneously.
Above-mentioned solution has following advantage.
The first, increased output, this is owing to can load and start described at least two parts individually, makes machine prepare to reduce by half necessary downtime, and has avoided buying too much automation equipment.The yarn that destroys recovers necessary shutdown, because they only relate to the part of machine, thereby greatly reduces the production loss that causes owing to this problem.Traditional self-acting mule of comparing limits two-part size and can obtain more power, has increased acceleration and speed.
The second, increased the quality of product.This is because two parts of machine can be leaned on distributor (divider) domination, thereby can load the rove of single doff, has reduced to keep the constant difficulty of product parameters in a period of time.
Better quality also is owing to lower moment of torsion on better overall power and the carriage transverse axis, and this is because motor better is positioned at the central authorities of appropriate section, and traditional position is the central authorities at whole self-acting mule.In fact, obtained the advantage in all short machines, but can also obtain the very high advantage of output.
Another advantage derives from the minimizing of the energy that uses.
In fact, the self-acting mule with at least two independent sectors according to the present invention is characterised in that:
-lower energy requirement is not owing on absorption peak and the left side be to take place simultaneously usually on the right side;
The use of-power is lower, because the consumption about less 20% of relevant power ratio tradition self-acting mule.As additional advantage, can sign more favourable contract with electric company.
Remarkable advantage with self-acting mule of at least two independent sectors is adaptive remarkable increase.
In fact, two parts can provide the spindle of varying number.For example, having the machine that adds up to 660 spindles can provide 440 and provide 220 spindles to left half to right half, thereby gives two doffs of the loading distributor on the right in them respectively, and give the left side only load a doff.
In addition, two parts can be used together or separately use.
In addition, two parts can aligned with each otherly be assembled, one opposite with another or even angled, for example become 90 °, thus according to the special demands that adapt to and use usage space better.
