Abstract

With conventional spinning machines, the empty bobbins have to be supplied to the machine in the correct orientation so that they can be placed on the input belts automatically. With such machines, it is therefore necessary to convey the bobbins to the spinning machine in mutually parallel containers. In order to be able to convey the bobbins from the spooler to the spinning machine in any type of container, the spinning machine is fitted with a device having a feed hopper (12) in which the bobbins can be previsionally stored lying at random. Linked to the feed hopper (12) is an elevator (9) with a multiplicity of horizontal support slats (10) which take individual bobbins (30) from the random heap and feed them to the input device (3) on the spinning machine.

Description

Method and device for feeding empty

Spinning sleeves

description

The invention relates to a method for feeding empty spinning tubes originating from a winding machine to a drawing-in device of a spinning machine, to which drawing-in device the spinning tubes are to be presented aligned parallel to one another. Furthermore, the invention relates to a device for feeding empty spinning tubes to a drawing-in device of a textile machine winding the empty spinning tubes with yarn, in particular for carrying out the previously specified method.

In the spinning mill, a winding machine is usually arranged after several spinning machines. The wound cops produced in the spinning machines are rewound in the winding machine to larger bobbins. As a result, empty spinning tubes are produced in the winding machine, which need to be examined for any remaining threads, sorted out and returned to the spinning machines. So far, the procedure is as follows. After the spinning tubes with residual threads have been sorted out, the usable spinning tubes are placed parallel to one another in specially designed spinning tube containers. The spinning tube containers, which have a width that corresponds approximately to the length of the spinning tubes, have a bottom that can be opened on their underside. The spinning tubes placed in the spinning tube containers are arranged with the containers transported to the spinning machine and positioned there on the feed device, after which the bottom of the sleeve container is then opened. The feed device of the spinning machine successively removes the spinning tubes, which are aligned parallel to one another, from the tube container. So that the sleeves are then automatically placed on the sleeve feed belt of the spinning machine, the sleeves are sorted in this device so that the large opening of the conical sleeves points downwards.

Although this type of feeding the empty spinning tubes on the spinning machine has now become established and in any case also represents an improvement over the feeding of the spinning tubes by hand, the known procedure has some disadvantages. For example, separate containers are necessary in order to transport the wound cops from the spinning machine to the winding machine, while the above-mentioned spinning tube containers must be used for the return transport of the unwound spinning tubes of the winding machine to the spinning machine. In addition to the fact that a number of spinning tube containers must always be in circulation, it is also necessary to transport them from the spinning machine to the splicing machine in an empty state, so that there are a number of transport routes which cannot be used per se. Furthermore, the sleeve boxes, which at least have a weight of approx. 30 kg when filled, have to be lifted onto the retraction device of the spinning machine in severe physical conditions, thus at least to a height of approx. 1.20 m.

It is therefore an object of the present invention to improve the method and the device of the type mentioned in the introduction in such a way that special spinning tube containers can be dispensed with. This object is achieved in that the spinning sleeves are transported in the unoriented state from the winding machine to the spinning machine, are temporarily stored there in the unoriented state and then automatically aligned parallel to one another and fed to the feed device in succession.

This solution has the advantage that no separate container is required for the transport of the spinning tubes from the winding machine to the spinning machine. It is also possible to use the bobbin wagon, which is normally used for the transport of the cops from the spinning machine to the winding machine, for the transport of the empty spinning tubes from the winding machine to the spinning machine, since the spinning tubes are only aligned in the correct position on the spinning machine. In this way, in addition to the special spinning sleeve containers, you also save empty runs of the bobbin wagon from the winding machine to the spinning machines.

In spinning machines which have two feed devices for the spinning sleeves arranged next to one another, according to an advantageous development of the method it is provided that the unoriented spinning sleeves are temporarily stored and aligned separately, the respectively aligned sleeves being counted, and wherein "if there is a numerical difference, the surplus spinning sleeves are automatically returned to the other intermediate store, which has the advantage that, if necessary, an equal number of spinning sleeves is fed to both drawing-in devices of the spinning machine without the operator having to pay particular attention to this.

With regard to the device, the object underlying the invention is achieved in that the Textile machine at least one buffer in the form of a container is provided, in which the spinning sleeves can be inserted in the unoriented state and that one of the container walls is at least partially designed as a vertical conveyor with an upward conveying direction, on which carrier bars horizontally aligned and parallel to one another and spaced apart from one another are provided.

This device is particularly suitable for carrying out the method according to the invention, since the empty spinning tubes originating from the winding machine e.g. can be transported to the spinning machine in a disordered state with the bobbin wagon and dumped there into the storage container. The vertical conveyor, which feeds the empty spinning tubes to the feeding device of the spinning machines, also aligns the spinning tubes in a parallel arrangement to one another. This is done in that the vertical conveyor forms a container wall and is provided with carrier bars which engage in the pile of empty spinning sleeves present in the storage container and mix these continuously until a spinning sleeve comes to rest on a carrier bar, which is then conveyed out of the storage container by the vertical conveyor becomes. The vertical conveyor thus has a dual function.

In a preferred manner, the container can have a bottom surface that is inclined downward toward the vertical conveyor. The inclination of this floor surface means that spinning sleeves are always in contact with the vertical conveyor and are mixed or taken along by the carrier bars. It has proven to be advantageous if the angle of inclination of the floor surface, measured relative to the horizontal, is approximately between 10 ° and 25 °, preferably 15 ° and 20 °. According to a preferred embodiment, the container can furthermore have two opposite side walls which converge in the direction of the container bottom and in the direction of the vertical conveyor. As a result, the pile of spinning tubes present in the container is fed to the vertical conveyor practically in a funnel-like manner, so that several spinning tubes are always involved in the mixing process up to the last spinning tube.

It is preferred if the distance between the side walls in the area of the vertical conveyor in the vicinity of the container bottom is greater than the length of a spinning tube and less than one and a half times the length of a spinning tube. This distance range has been found to be favorable in order to accelerate the separation of the spinning tubes by the vertical conveyor.

According to a preferred embodiment of the invention, a distance can be provided between the edge of the container bottom facing the vertical conveyor and the vertical conveyor that is greater than the width of a carrier bar and smaller than the sum of the width of a carrier bar and the smallest diameter of a spinning tube. In this way it is possible that when a carrier bar moves upwards past the edge of the container bottom, a spinning sleeve lying on the container bottom falls into the gap between the vertical conveyor and the container bottom and falls on the subsequent lower carrier bar. This also further increases the separation performance of the device.

If, according to a preferred embodiment, the length of a carrier bar is greater than the length of a spinning tube and less than one and a half times the length of a spinning tube, on the one hand it does not depend on the exact position of a spinning tube in order to position it correctly To be taken vertically, while on the other hand a mutual jamming of the spinning sleeves is prevented.

Although it would also be conceivable to provide chains with straps or a conveyor belt as the vertical conveyor, according to a preferred construction the vertical conveyor has at least one circumferential belt to which the carrier strips are fastened. To attach the carrier strips to the belt or belts, it is advantageous if blocks are cast onto the belt, on which the carrier strips are screwed tight.

Although a pair of chains running in parallel would also be suitable, it has proven to be advantageous if the vertical conveyor has two belts designed as toothed belts. Although it would also be conceivable to fasten the driver bars to a wide conveyor belt, the width of which extends over the entire length of the driver bars, it is preferred if the belt or belts are narrower than the driver bars and that the belt or belts laterally from fixed sliding walls are framed, on which the driver strips are slidably held by the belt. The lateral sliding walls extend in a plane parallel to the longitudinal extension of the driver strips, so that the driver strips can slide along with their portions projecting laterally beyond the belt on the sliding walls. The sliding walls form part of the container wall of the storage container.

In order to be able to prevent lifting of the carrier strips from the sliding walls in a simple manner even when using narrow toothed belts, it is preferred that guide shoulders are formed on the two free ends of the carrier strips, which in the side next to the Engage guide rails arranged vertically.

In a particularly favorable manner, the guide rails can be formed by the side walls of the container, which is adjacent to the vertical conveyor.

In order to avoid that the vertical conveyor conveys two spinning tubes directly one above the other from the container, it would be conceivable to make the vertical distance between two carrier bars so small that only one spinning tube can be taken along; However, it is preferred that wiping cams are arranged on the sliding walls, which scrape off the upper of two spinning sleeves lying one above the other on a carrier bar, so that this falls back into the container and is only conveyed further into the spinning sleeve lying directly on the carrier bar.

In order to avoid a collision of the wiping cams with the driver strips, corresponding recesses can be provided in the driver strips. Another possibility would be to store the stripping cams spring-supported so that they are pushed back behind the sliding walls by the driver strips.

In order to ensure a particularly stable position of the spinning sleeves lying directly on the carrier bars during upward transport by means of the vertical conveyor, it is expedient if the upper side of the carrier bars is designed such that the spinning tubes rest along a line of contact on the top of the carrier bars, which line of contact a distance of which the belt has side-framing sliding walls, which is larger than the largest radius of the Spinning sleeves. Thus, the spinning sleeves lying directly on the carrier bars also lie directly on the sliding walls, which already counteracts the tendency that two spinning sleeves are transported one above the other. Should this nevertheless occur, it is sufficient if the scraper cam pushes the upper spinning sleeve away from the sliding walls by only a small amount, namely until the center of gravity of the upper spinning sleeve lies on the side of the apex of the lower spinning sleeve opposite the sliding walls.

For feeding the spinning tubes to the feed device of the spinning machine, it is expedient if a rear wall is attached to the side of the vertical conveyor facing away from the container and with its conveying direction pointing downwards, the back wall of which is smaller than the smallest diameter of a spinning tube. In this way, a shaft is formed on the rear side of the vertical conveyor, in which the spinning sleeves fall onto the underside of the front driving bar in the transport direction and are guided downward in the shaft according to the speed of the vertical conveyor.

In this context, it is advantageous if lateral, downwardly converging guide strips are provided on the side of the rear wall facing the vertical conveyor. These guide strips center the spinning sleeves and bring them into a convenient transfer position for the feed device.

If the device is to be provided for spinning machines, which has two feed devices arranged side by side, it is advantageous if the device has two vertical conveyors side by side includes. Although it would also be possible to provide two separate containers for the respective vertical conveyors, it is preferred that a common container is provided which has a dividing wall through which an intermediate store of approximately the same size is assigned to each of the vertical conveyors. This has the advantage that the unordered spinning sleeves can be emptied from a trolley into a container for loading the device without having to pay attention to a special distribution of the spinning sleeves.

It has proven to be advantageous if the height of the partition is approximately one third of the height of the side walls of the container. If the container is filled with spinning sleeves from a bobbin wagon, the filling level is generally higher than the partition, so that when the sleeve mountain built up above the partition is dismantled, the spinning sleeves are distributed approximately equally in number in both container halves.

In order to be able to feed a desired number of spinning tubes to the two feeding devices of the spinning machines as required, it is expedient if a counter is provided for counting the spinning tubes transported with one vertical conveyor each and if a further depending on the vertical side of the container facing the container Counter controllable ejector is provided for throwing back spinning tubes into the container. This ejector can either function mechanically with an extendable ejector pin or preferably pneumatically with a blow nozzle.

In this way, even if both vertical conveyors have a common drive, the supply of spinning sleeves to one of the feeding devices can be stopped while the other feeding device Spinning machine still be fed spinning sleeves. In this context, it is particularly favorable if a slide is provided below the ejectors, which is inclined downwards towards the intermediate storage of the other vertical conveyor and onto which the spinning sleeves dropped by an ejector fall. Since the surplus spinning sleeves of one buffer store thus get into the other buffer store, it is possible to feed the same number of spinning sleeves to both drawing-in devices of the spinning machine and yet to empty the container completely.

TM to be able to empty larger bobbin wagons into the container in a simple manner, it is advantageous if a lifting device for lifting and tipping a transport carriage for the spinning sleeves is provided on the side of the container facing away from the conveyor belt. This device can also be provided for slowly lowering the transport trolley when it is being filled with wound cops coming from the spinning machine, so that it is no longer necessary, as was previously the case, to provide a spring base in the bobbin trolley which moves downward with increasing weight .

An exemplary embodiment of the invention is explained in more detail below with reference to a drawing. Show it:

2 shows a schematic representation of a top view of the device from FIG. 1,

Fig. 3 is an enlarged view of a section along the line III-III of Fig. 2 with a view of the Vertical conveyor,

Fig. 4 in an enlarged view the detail IV of Fig. 3, and

5 shows a horizontal section through the device along the line V-V in FIG. 3rd

In Fig. 1, a conventional spinning machine 1 is schematically shown in a side view, to which a device according to the invention is attached.

The spinning machine 1 comprises, on a front part 2, an automatic feed 3 for the correctly positioned spinning tubes and an adjoining shaft 4 with the possibility of turning the spinning tubes. Below the shaft is the sleeve feed belt 5, with which the spinning sleeves are fed to the individual spinning stations, which are not shown here for the sake of clarity.

In the other direction, the sleeve infeed conveyor is followed by a further conveyor belt 6, directed obliquely upwards, with which the sleeves wound at the spinning positions, the so-called cops or bobbins, are placed in a bobbin wagon 7 which is ready. In the spinning machines 1 just described, the empty spinning tubes have so far been arranged parallel to one another in so-called tube containers and fed in the correct position.

In the subject matter of the present invention, the sleeve containers, the position of which is indicated in FIGS. 1 and 2 by dashed lines 8, are replaced by a device which is described in more detail below. Since the spinning machine 1, as can be seen from FIG. 2, has two feeders 3 and 3 'arranged next to one another, the device 2 according to the invention also has vertical conveyors 9 and 9' arranged next to one another. The vertical conveyors essentially consist of horizontally arranged carrier bars 10 and 10 'attached to vertically rotating belts 11. Furthermore, the vertical conveyors 9 and 9 'form a vertical wall of a storage container 12 provided for receiving the sleeves. The storage container 12 extends over the entire width of both vertical conveyors 9 and 9' arranged next to one another and has a base 13 which is inclined towards the vertical conveyors. The angle of inclination © of the floor to the horizontal is approximately 20 ° in the exemplary embodiment shown here.

Furthermore, the storage container 2 is delimited by two side walls 14 and 15, which run on the one hand from above in a funnel-like manner to the bottom 3 and on the other hand also funnel-like towards the front to the vertical conveyors 9 and 9 '. In the middle, the storage container 12 is divided by a partition 16 into two intermediate stores 17 and 18 assigned to the respective vertical conveyors 9 and 9 '. The height of the partition is only about a third of the height of the two side walls 14 and 15. At the end of the storage container 12 facing away from the conveyor belts, the two side walls 14 and 15 are at a distance from one another which is greater than the width of the bobbin wagon 7 On this side of the storage container 12 there is also a lifting and tilting device 19 with which the bobbin trolley 7 can be gripped, lifted and pivoted about a horizontal axis 20 lying at the height of the storage container 12 until the side wall 21 of the bobbin trolley 7 facing the storage container 12 lies in one plane with the bottom 13 of the storage container 12. Due to the hydraulic cylinder 23 acting on the carrying fork 22, the bobbin wagon 12 can also be stopped or continuously lowered again in any intermediate positions.

3 to 5, the vertical conveyors and their assignment to the storage container are now explained in more detail.

The driver strips 10 and 10 'of the vertical conveyor are each attached to two pairs of rotating toothed belts 11, 11', plastic blocks 24 being cast onto the toothed belts 11, 11 ', to which the driver strips 10, 10' are screwed. The toothed belts 11 and 11 'are framed laterally by sliding walls 25, 26 and 27, on which the driver strips 10, 10' slide along. If the carrier strips 10, 10 'are viewed from the storage container 12, their upper side 28 is formed obliquely, so that the line of contact 29 a sleeve 30 resting on a carrier strip 10 is at a distance a which is greater than the largest radius R of the conical spinning sleeves 30. In this way, the sleeves 30 are always held against the sliding walls 25, 26 and 27 which laterally frame the toothed belt 11.

The width B of a driver strip 10 is smaller than the largest diameter D of a sleeve 30, but larger than the largest radius R of a sleeve 30.

The distance A between the front edge 31 of the bottom 13 of the storage container 12 facing the vertical conveyor 9 and the sliding walls 25 to 27 of the vertical conveyor 9 is greater than the width B of a carrier bar 10 and smaller than the largest diameter D of a spinning sleeve 30. In any case, the distance A is smaller than the sum of the smallest diameter d of a sleeve 30 and the width B of a driver strip 10. As can be seen particularly well from FIG. 4, in the upper region of the vertical conveyor 9, a threaded pin 32 is screwed into one of the sliding walls 25, but this screw projects slightly beyond the front of the sliding walls. So that the driver strips 10 are not hindered by the threaded pin 32, corresponding recesses are provided in the driver strips 10, which are, however, not shown in the drawing for the sake of clarity.

An ejector 33 is arranged above the threaded pin 32 and comprises an ejector pin 35 which can be actuated and moved by means of a pneumatic short-stroke cylinder 34. The ejector 33 is, as will be explained later, connected to a counting device which comprises a light barrier 36 which is attached to the side of the vertical conveyor 9 facing away from the storage container 12 and which counts spinning sleeves conveyed by the vertical conveyor 9.

As can be seen in this connection from FIGS. 1 and 2, a slide 37, 37 'is provided for each vertical conveyor 9, 9' below the ejector 33, onto which the spinning sleeves dropped by means of the ejector 33 fall. The sleeves 30 which have fallen onto the chutes 37, 37 'slide along the chute into the intermediate storage 18 or 17 of the other vertical conveyor 9' or 9 (see FIG. 1).

On the side of the vertical conveyor 9, 9 'facing away from the storage container 12, a rear wall 38 is arranged which, together with the rear of the vertical conveyor, forms a shaft 39 in which the sleeves 30 are conveyed downwards, the sleeves then being moved upwards lie on the swept undersides 40 of the driver strips 10, 10 '. The distance from the rear wall 38 to the Driver strips 10, 10 'is selected so that the sleeves 30 cannot fall down.

At the lower deflection end of the vertical conveyor 9, 9 ', a feed channel 41 is provided, in which the sleeves 30 are placed parallel to one another and are drawn in by the feed device 3, 3' of the spinning machine 1, which is no longer shown because it is known.

The operation and functioning of the device according to the invention is explained in more detail below.

On the winding machine, not shown in the drawing, the bobbin wagon 7 is filled with the empty spinning tubes that are produced there. Since the bobbin wagon is larger in all dimensions than the spinning sleeves to be transported, the spinning sleeves are disordered and mixed up in the bobbin wagon 7. The bobbin wagon filled in this way is then moved from the winding machine to the spinning machines, where it is emptied into the storage container 12 together with the lifting and tilting device 19. Since the partition 16 between the two intermediate stores 17 and 18 of the storage container is not as high as the two side walls, the number of spinning sleeves 30 is distributed relatively well between the two intermediate stores 17 and 18, since the spinning sleeves are also above the partition 16 when the storage container 12 is full lie.

When the device is put into operation, the driver strips 10, 10 ′ facing the storage container 12 move upward. The unordered pile of spinning sleeves present in the store is mixed until a sleeve parallel to the vertical conveyor is also present on the front edge 31 of the storage container bottom 13. Such a sleeve will then gripped by a driver strip 10 or 10 'and conveyed upwards. This process is repeated until the intermediate stores 17, 18 of the storage container 12 are completely emptied, the obliquely arranged bottom 13 ensuring that all spinning tubes are fed to the vertical conveyors 9 and 9 ', respectively.

Now it can happen that two spinning tubes lie one above the other on a carrier bar 10 or 10 ', which is not desirable. Such a pair of spinning sleeves passes through the setscrew 32 in the upper region of a vertical conveyor 9 or 9 ', as a result of which the spinning sleeve lying above is pressed a small amount away from the sliding wall 36. This small amount is sufficient for the upper spinning sleeve 30 to become "overweight" and to fall down into the storage container 12 from the lower spinning sleeve. The spinning sleeve underneath is also pushed off the sliding wall by the grub screw 32, but then returns to the sliding wall 26, since the width B of the carrier strips is dimensioned such that the spinning sleeves 30 are not knocked down by the grub screw 32 from the top 28 thereof.

The spinning sleeves 30 conveyed upwards fall on the side facing away from the storage container 12 into the shaft 39 formed by the vertical conveyor 9 or 9 'and the rear wall 38, whereby they are collected from the underside 40 of the leading carrier bar 10 or 10' and down are transported where the spinning sleeves pass through an inclined surface 42 and a scraper brush 43 into the feed channel 41. From there, the known pull-in device of the known spinning machines takes over the further transport of the spinning tubes to the individual spinning positions.

Since with the spinning sleeves during the downward transport in the shaft 39 are centered on the feed channel 41, guide strips 44 tapering downward are provided on the rear wall 38.

In order on the one hand to increase the sorting capacity of the vertical conveyors 9, 9 'and on the other hand to prevent spinning sleeves from jamming, the width of the intermediate store, that is the distance between the partition 16 and a side wall 14 or 15 in the region of the front edge 31 of the base 13 chosen so that it corresponds to one and a half times the length of a spinning sleeve 30. As can be seen from FIG. 5, the side walls 14 and 15 as well as the partition 16 serve to guide the driver strips 10, 10 ', which have corresponding guide shoulders 45 at their free ends.

While the spinning tubes are being sorted and fed, they are counted by means of the light barrier 36. If now e.g. If the first intermediate store is empty and is only conveyed from the other intermediate store 18, the numerical difference is compensated for as follows.

Due to the numerical difference determined by the light barriers 36 and 36 ', the ejector 33 is actuated, the ejector pin 35 throwing the spinning sleeves off the respective carrier bars 10 and 10'. These thrown-down spinning sleeves 30 pass via the chute 37 into the respective other intermediate store, that is to say into the empty intermediate store 17, which is filled up in this way, so that the other vertical conveyor again feeds empty spinning sleeves to the other feed of the spinning machine In this way, an inaccurate distribution of the spinning sleeves present in the two intermediate stores 17 and 18 in a disordered manner can be compensated for. After all spinning positions of the spinning machine have been supplied with empty spinning sleeves, the spinning machine can work in the usual way. The wound sleeves, i.e. the cops or bobbins, are then over the sleeve feed belt. 5 and the conveyor belt 6 are conveyed out of the machine and get into the bobbin wagon 7. While in conventional bobbin wagons 7 a spring base was always provided in order to reduce the drop height of the first heads to be placed in the bobbin wagon 7, this is no longer the case with the device according to the invention necessary because the bobbin wagon with the lifting and tilting device can be slowly pivoted down from the position shown in dashed lines in FIG. 1 during the filling and can finally be set down on the ground without the cops having to travel greater heights.

From all this it is clear that the loading and disposal of the spinning machines with sleeves or cops with the same transport container, namely the bobbin wagon, can be carried out without any empty paths. Although not described, it is also conceivable to use the device according to the invention consisting of storage container 12 and vertical conveyor 9 in connection with a closed composite system in which the empty tubes are conveyed from the winding machine via a conveyor belt into the storage container 12 and only sorted there and then Feeder 3 of the spinning machine 1 are fed in the correct position.

Instead of an ejector pin 35, a controlled blowing nozzle can advantageously also be used as an ejector.
