Method and device for automatically requesting

Spools of thread (Kötzern) %

The invention relates to a method and a method

direction üura automatic conveying of garnishes or kötzern from a spinning machine to an automatic reel.

There are several automatic ones in the spinning industry lately Spinning processes and facilities have been improved or created in order to increase the yield of the spinning machines, To reduce the amount of manual labor and the quality of the products at least to maintain; some of these tried out f The leading institutions have been taken over in practice. In (known institutions of the type described above it was It is customary to bring the kötzer wrapped with yarn and replaced from the spinning machine into a box before they are in it Box are forwarded by a conveyor, or the to bring the filled G-arnkötzer alone onto a conveyor which, one after the other, uses an automatic reel to unwind the

Feeds yarn. However, these "known methods" have the following Disadvantage:

a) Since a box to be used can be moved by hand rriul-, it is impossible to automate the operation between the spinning machine and the automatic reel.

b) The arrangement of the Kötzer is disturbed because of the entanglement of the cut yarn ends, resulting in an undesirable Moving or jamming of the Kötzer on their way of transport

^ can lead.

c) Purely the elimination of those who are underweight Kötzer requires a considerable amount of manual labor.

Despite - or possibly because of - the above Disadvantages so far no device has been offered or used that has a spinning machine and an automatic na & pei connects completely automatically with regard to the transport of the yarn bobbins, and these disadvantages represent a manufacturing ^ bottleneck, the complete automation of the spinning process made impossible to unwind the spun yarn.

The invention is based on the object of a method and a device for the complete automation of the work processes between the spinning, and the reeling of the yarn to be carried out, the Kötzer from the spinning machine without Manual labor of the automatic. Reel to be fed.

Referring to the overall presentation of the erfindungsge- {mäJ3en device is said that the blocks shown with one-dot chain lines represent 1 automatic spinning machines. The fully spun yarn bobbins or cops in these spinning machines are replaced by grippers,. those on an endless chain of an automatic. Bobbin changer

(not shown) are attached; this endless chain moves in an orbit and the full spools of thread or kötzer are picked up by magnets attached to an endless conveyor sit; the captured twine hang on the magnet this conveyor to which they are fed through a guide tube; this endless or self-contained conveyor 2 moves on a path around the spinning machine.

^ In detail, the Kötzer 3, as shown in Fig. 2, each provided at their upper ends with a magnetizable part 4, which is attracted by one of the magnets 5 arranged at regular intervals on the endless conveyor 2, so that the Kötzer of the endless conveyor are conveyed in a predetermined direction while hanging vertically downward on the magnet. At a fixed point in the area of one end of the spinning machine, a stripping stop 6 protrudes into the path of movement of the hanging Kötzer. When a Kötzer 3 strikes the stop 6 with its upper end, it is held in place by the ψ stop and its magnetic part 4 at the upper end is torn loose from the magnet 5 on the endless conveyor, which is steadily moving in the direction of the in FIG. 2 arrow continues to move. As a result of this stripping, the Kötzer 3 falls down under the action of gravity. The exact position of the falling Kötzers 3 is set by a fixed guide in such a way that the Kötzer falls exactly into one of the Kötzer mountings 9, which one behind the other on a tape

209811 / 0E85

Conveyor 6 is standing, which maintains the KÖtzer transport level or moved below the ground.

Each Kötzer holder 9 consists - as in Pig. 3 shown from a plastic hollow cylinder 11 and a ^{heavy iron ring 10 arranged on the lower part of this Z3 r} linder. The iron ring should keep the center of gravity of the holder as low as possible so that this holder, together with a Kötzer introduced into it on the conveyor belt, is always in a straight vertical position Position j remains; In addition, the holder should also be usable together with a belt conveyor in which the holder is through

. Magnet is held on the conveyor. Be weight-wise the brackets are balanced as well as possible so that their weight. differences lie within small tolerances and the subsequent weighing of the yarn coats with the brackets that hold them (which will be described in more detail later) by larger ones Differences in weight cannot be adversely affected.

As seen from Fig. 4, the holders 9 which is mounted at a fixed location pivotable relative to the belt conveyor while being held j a certain time on the belt conveyor 8 below the conveyor floor in a tilted number by means of a stop lever 12 and accumulated. In Fig. 5, a detector device 13 is shown, which consists of the combination of a light source and a photoelectric cell. This detector device 13 acts such that when

209811/0585

Interruption of the light beam between ^{1 of} the light source and the photoelectric cell by the magnet 5 »on which the Kötzer 3 hangs, the device is electrically energized with the relevant stop levers 12 and 12 · coupled solenoids 14 and 14 '(see Fig. 4) The solenoids cause the stop levers to pivot in the direction of the conveyor 6, so that the levers then hold the brackets 9. The brackets 9 are consequently held temporarily exactly below the Eötzer guide 7 on the further circulating conveyor L ^; Kö ^ zer;> through the stationary! Guide 7 into the holder 9, 'ieiin the magnet has stepped out of the beam path of the detector device 15 and the photoelectric cell is illuminated again wildly, the device switches the excitation of the solenoids 14- and V ₁ - 'from, so that the stop levers 12 and 12' under the action of springs 15 and 15 'are reversed in their dashed lines fall back to pictorial rest positions. The brackets 9 are then grounded by the belt conveyor L · in the direction of the in Ifig. 4 ψ drawn arrow moves further. The detector device \ is actuated again by the following magnet of the conveyor 2 and the Kötzer carried by this magnet falls into the holder that was then held by the stop lever under the stripping point. This process is repeated whenever the magnets are moved through the detector device; in this way become the individual

Kötzer one after the other in the brackets in an even sequence brought in by dropping it.

Since in this lalle the holder intended to receive a falling poo is held by the stop lever 12 only for a short period of time, which corresponds to the time during which the magnet 5 passes through the D.etektqrvorrichtung, it proves to be advantageous to exclude a accidental and undesired falling of the Kötzers at ä a slight deviation of the relative position of the unstoppable from the λ stop lever holder, a plurality of holders close to one another lying in front of the stop lever to stop, so that the first of the further holders in a very short time in the right to receive a Kötzers Position can be brought. For this purpose, a plate or diaphragm plate 16 blocking the light beam of the detector device and having a length corresponding to the length of several magnets 5 is arranged on the endless conveyor 2 at a point which arrives at the detector device with a time advance or earlier than the Kötzer (cf. Fig. 5). In this way the hold-open time *

at least some of the brackets 9 on the stop lever 12 are extended in that the detector device remains in the working state, that is to say the state in which the stop lever 12 is locked, for a longer period of time. It is thus possible to collect ^{several holders on the I 1} strap 3 in front of the stop lever 12

or "accumulate". The stop lever 12 ', as shown in Fig. 1 and Pig. 4 is shown, which is at the rear or inlet end of the straight section of the belt conveyor 8 is located with electrical controls in a control box 17 (Pig.1), which bring it into the blocked position when the endless spinning machine conveyors 2 are at a standstill; the stop levers 12 and 12 · are however with the detector devices 13 assigned to them are coupled in terms of their effectiveness when these detector devices 13 ^ speaking light beam blocking plates 16 are operated, which are attached to the endless spinning machine conveyors 2. The effective coupling or connection between the stop lever 12 'and the mentioned electrical control element, and the connections between the stop levers 12 and 12 * and the Detector devices 13 are automatically with the help of electrical Switching devices switched so that the brackets are successively brought onto the belt conveyor 8 as soon as of the spinning machine / conveyors 2 Kötzer are promoted.

As in fig. 1, the brackets 9 are each one Contain Kötzer 3 (marked in Pig. 1 by double circles), and which are transported by the belt conveyor 8, placed on a rotating plate disk 18, from which it rotated or pivoted and pushed onto another belt conveyor 20, while their respective position by a stationary

Guide 19 is corrected exactly.

At the transfer end of the belt conveyor 20 is a gate direction provided to the port movement direction of the Kötzer supporting brackets in the horizontal and vertical directions change. This device, more precisely in the Pig. 6 to 9 are shown is, comprises a chain 21 revolving over a drive sprocket 23 and a deflection sprocket 22, which by any motorized drive acting on the drive sprocket 23 is driven. The chain 21 is in a guide frame,

housed, which limits the path of movement of this chain and attached in suitable spaces on the chain carrier leads. Each carrier 25 consists of a base plate 26, one vertically upwardly projecting support plate 27 j which differs from that Edge of the base plate, which is closer to the chain, and several suitable band-like pingers 28, from the rear edge of the vertical retaining plate 27 at right angles to this edge, i.e. approximately horizontally, go out, line fixed plate 29 is arranged at a small distance from the chain conveyor 21 and serves as ^ j "Transfer plate". This fixed plate is made with strips- ^ shaped guide members 30,31 and 32 small height, which - as can be seen from the illustration - the brackets 9 on the Lead plate 29. The guide or guide element 31 has a shorter length, so that there is no obstacle to the transverse movement of the carrier 25 forms with a recorded Kötzer. The band-

209811/0585

conveyor 20 is also provided with guides 33 along its side edges. A leaf spring 34 is provided in order to bring a holder 9, which has been brought along the guide 31 and stopped when it comes into contact with the Ie it organ y'l, into a precisely defined position. Another leaf spring i, 3 is used to hold the holder in this position. Hit 36 is a push button of a liikroschalters, which "senses" the accumulation of holders. The movements of this

^ Button are connected electrically so, the drive for the coupled Kettenför- W those.

When operating the device as just described was, first the brackets 9 between the pointed End of the button 36 and the guide element 32 before the start of the work: process accumulated and then brought up v / ground further brackets bJ by the belt conveyor. If the brought further Holders apply pressure and the tip end of button 56 of the microswitch is pushed aside, begins "to work the chain 21 and the supports accumulated on the fixed plate 29 * are grounded by the fingers 28 of the corresponding, gripped on the chain attached carrier 25 and thus taken one after the other by the carriers 25. V / ie yourself from the figure, the bottom plate 26 of the runs Carrier 25 just below the stationary plate 29 through, while the fingers 2ü of the wearer over the guide members 30 and

sweep past. The holder recorded in this way remains Run down from the edge of the stationary plate 29 on the base plate 26 of the movable carrier 25. During the process ens is the holder by the leaf spring 35 against the vertically upwardly projecting support plate 27 of the carrier printed, so da.3 it is secured against tipping or falling from the carrier.

As previously stated, the space between the front or pointed end of the button 36 and the guide member 32 is always filled with holders. This is necessary for the exact 'control of the positions of the holders, which ensure a perfect transition of the holders into the carrier 25 one after the other. Since ^- the brackets on the stationary plate 29 are continuously pushed forward by the other brackets still on the conveyor belt 20, the space freed up by the carrier 25 when the first bracket is removed from the stationary plate is immediately closed by the following brackets. ; there? entire installation area on | the stationary plate is always fully occupied with brackets. j These holders are held on the stationary plate by the leaf spring 34 until they are removed from the fingers 28 of the carrier 25.

The movement of the chain 21 is interrupted when the space in front of the sensor 36 of the micro-holder is free of brackets.

209811/0585

The chain 21 is guided by the guide 24 in such a way that it is in an area in which it is directly attached to the stationary Plate 29 passes, and also in an area in which the brackets are dispensed from the respective carriers after they were brought to a higher point by the chain (see 9), runs horizontally, so that the girders are also there be moved horizontally. The middle section of the guide 2 ^ between the two horizontal. Path areas of the chain is in suitably inclined, in each case according to the local conditions.

Around the mounts in the raised section of the chain take off, a stationary, inclined, comb-like gripper 57 is provided, which - as in Pig. 8 illustrates the Holder can be removed from the carrier without touching the finger carrier 28 of the carrier. That way The bracket removed from the carrier is then transferred to another belt conveyor 59 by being guided on the bracket guide rail 58 convicted. It should be clear that all incoming. "Brackets along the aforementioned horizontal and inclined track sections are moved, regardless of whether they contain Kötzer or not.

Returning to FIG. 1, it is to be said that at the "front" transfer end of the belt conveyor 39 a device is intended for weight testing and elimination for the Kötzer,

The purpose of the weight and elimination device is to keep the To determine the weight of the Kötzer with the brackets receiving them, one after the other, and a separation between take the pits with the prescribed weight and those with an underweight. How this weight checking device works is made with reference to Pig. 10 and 11 explained in more detail.

The Kötzer 5 held vertically in the holder 9 is brought together with its holder by a circumferential driver uf a weighing pan 42. The circumferential driver 41 has a recess ^ -5 on its circumference, it is driven by a drive which is controlled with a button 44 of a limit switch. A stationary plate is denoted by the beaugsmark 5, the swivel bearing of a balance beam 47 is denoted by 46, a photoelectric cable is denoted by <fö and a conveyor is denoted by 49 for the further conveyance of the weighed Kötzer and brackets. A guide plate 50 is mounted as a separating wall on the conveyor 49, it has on the inlet side a blade-(-shaped link 51 which is pivotally supported on the side facing the cradle tray i side of the plate. When the pushbutton 44 of the end or limit switch by a bracket 9 is actuated, which is moved by the conveyor 39, and the brackets already previously accumulated in the space between the driver 41 and a point directly on the button 44 against the

outer circumference of the driver are pressed by the moving conveyor belt 39., the drive mechanism X for the driver is set in motion, which rotates the driver 41 in the direction of the arrow drawn. The holder which is furthest forward is then gripped by the recess O in the driver and pushed from the stationary plate 45 onto the weighing pan ', 2 by a sliding roller 52 mounted at the end of a lever; the pressure or slide foil is coupled to the rotating driver and protrudes slightly radially over its circumference. The last weighed tea still standing on the weighing bowl is pushed down from the weighing bowl and brought onto the conveyor V9 to be transported further by it.

It should be clear that the on the weighing bowl applied and a Kötzer containing bracket now from both her previous and the following bracket is completely independent. Then a lock or a stop 53 of the balance beam 47 is activated by the action of a (not shown) magnet is withdrawn, which is excited simultaneously with the rotation of the driver 41. The weighing bowl / j-2 can Lower yourself down to determine your weight. After the weighing has been carried out, the locking stop 53 after switching, the magnet returns to its division of engagement brought and the weighing pan comes back to its original position to accommodate the following bracket.

weighing the total weight of the kötz and its holder is equal to or greater than a prescribed value. a light beam which is switched on by electrical switching devices only for the duration of the weighing in order to illuminate the photoelectric cell 40 is interrupted by the balance beam and no signal is generated. However, if the weight is less than the prescribed value, the balance beam does not interrupt the light source, so that: 3 it can illuminate the photoelectric cell and an electrical signal is sent out, which a drive device Y to operate the ™ acts as a V / oak Controls handlebar 51, which gives this handlebar an oscillating movement. In the first mentioned case, in which the total weight of the Kötzers and its holder was equal to or greater than the prescribed value, the handlebar 51 remained in the position shown in Pig.10 with full lines, in which he called the holder as "BOrmalfall" can run on the conveyor 49. In the other case, however, in which the weight is below the prescribed. Value is, ^ the link 51 in the λ shown with dashed lines

Position (Fig.10) pivoted; the underweight kötzer is guided with its holder into a path of the conveyor belt 49, which is separated from the normal trajectory. on this way int it possible to keep the underweight poop to separate from those Kötzern, or to weed out the one Have a normal weight: this process happens easily, automatically and also inevitably.

The conveyor 49 is connected to or provided with an accumulation conveyor 54 at its "front" transfer end. This accumulation conveyor has the same as the conveyor * _; -9 a stationary central partition or guide plate 55, which separates the passage for the brackets into a right-hand branch R and a left-hand branch L, each seen in the direction of the movement of the brackets. 'The conveyor 5ν is constantly ^ driven in order to continue to lead the holders with putties located therein ^ from the conveyor 49. If the automatic reel 56 does not report the need for a further Kötzer, the brackets carrying the Kötzer in the L-branch of the bracket guide, ie the movement path for the Kötzer normal weight, stopped by a stop 5i and the brackets delivered one after the other , are accumulated in this rope of the conveyor 54 and on a stationary plate 59, which following. the. Conveyor 54 is arranged (see Fig. 1). If, however, the automatic reel 56 needs a further "Kötzer", the stop stop 51 is opened by electrical actuating P organs via which the stop stop is connected to the automatic reel. The holders accumulated on the conveyor 5h can then be placed on the stationary plate 59 are pushed on, whereby they align themselves in a single row one behind the other, for which a guide 58 contributes; the brackets are advanced by the brackets behind them and by devices to be described below

to pass on one after the other and evenly, it is known to use a stationary guide rail or guide or rotating guide rollers. However, such well-known cases have the disadvantage that a large number of the Z3 ^r cylindrical bodies are mutually forcibly pushed together in front of the transfer point and can become jammed as a result of the friction between them, so that it is either impossible or at least difficult to see them in a circle Carrying on the body one after the other and one at a time without being forced. This main part was a great difficulty in carrying out a continuous and automatic work or transport process. .

According to the present invention, however, it has become common The disadvantage of using a single guide rail 58 is avoided who is able 'to use the brackets individually and without Force to forward. The structure and training of this guide 58 is now with reference to the Pig. 12 and 13 described. The guide 58 consists of a sheet or tape spring

209811/0585

The and is installed in such a way that a part of the spring which comes into contact with the accumulated supports can be deflected elastically both inwards and outwards. At a certain point, however, the elastic guide 5ü is supported rigidly by a support member GO; together with a fixed guide 61 opposite it, it forms a holding passage ..,.

tk As can be seen from FIG. 13, the elastic guide 58 is

As a result, the brackets will jam avoided and the brackets can be in proper ■ Proceed as follows: Remove the stop clip 57 one at a time be continued on the plate 59 between the guides.

The management method just described in accordance with the present Invention could only be found after extensive experiments ^ will; it may because of the new and unique - described above - Avoid the disadvantage of the usual measures and for an easy and steady porting of the arrangement Take care of advancing the mounts one by one.

Furthermore, one can see from the S ¹ Ig. 1 how the Kötzer-carrying brackets are advanced on the stationary plate 59 and moved in the direction of the automatic reel 56 with the help of a chain conveyor 52, which takes the brackets with it through the force of attraction between the iron rings of these brackets {and magnets attached to the chain conveyor. j

Then the brackets containing the Kötzer become automatic by a circumferential component 63 that requires kötzeren taken one after the other and only the Kötzer fall through a f.'jti'nung 34 which is provided in the exact area of the .Fördervorrichtung 63 where the Kötzer is conveyed in the automatic reel is effected. ■
