    Description: The invention relates to a winding machine for winding slivers according to the preamble of claim 1. Furthermore, the invention relates to a method for operating a winding machine.
    The current feeding of flat combing machines is done by cotton wool, which were previously generated in winding machines from individual bands. For this purpose, the winding machine receives the template in ribbon form of at least one route, the template is cached in round or rectangular cans. The winding machine usually consists of a winding unit with at least two winding rollers on which the lap roll is formed by means of a sleeve. The sleeve is held in a clamping manner laterally by two reel disks, wherein the reel disc can be moved by means of at least one carriage along a solid guide. The method of the reel disc or the carriage via laterally arranged pneumatic cylinder, with which also the winding pressure, so the pressure of the sleeve or of the begun roll against the winding rollers, is generated. When a predetermined length of cotton wool, for example 300 m to 400 m, has been wound up, the cotton wool is torn off, for example by slowing down the upstream calendering or pressure rollers. The winding is then transported to the prior art by means of lifting table and / or subsequent tilting of the winding support surface on a trolley, with which the winding is transported to the combing machine.
    Alternative winding devices use an endless circulating belt for winding the cotton wool. The ejection process of the finished lap roll is also very complicated and expensive.
    It is also known from the prior art to convey the reel by means of ejector from the gusset between the winding rollers on a support surface. The known solutions have the property that the delivery height of the winding machine and the receiving height of the subsequent combing machine are to be matched. As soon as these heights differ, there are other devices with which the cotton wraps are conveyed, for example, to the intermediate transport car.
    After EP 1961685 B1, a combined lifting / pivoting device for the lap roll is provided, with which the lap roll can be transported despite different heights on the trolley. The device is mechanically and control technology very complex and expensive, and extends the entire winding machine by at least one meter, which is undesirable due to the space situation in the spinning.
    It is an object of the invention to provide a winding machine that can carry the finished cotton roll on a trolley with little technical effort.
    It is another object of the invention to provide an associated method for operating such a winding machine.
    The invention solves the problem by the teaching of claim 1 and 11; Further advantageous features of the invention are characterized by the features of the dependent claims.
    According to the technical teaching according to claim 1, the winding machine for winding fiber slivers comprises a winding unit, on or in which a lap roll is formed by means of a winding tube, wherein the winding tube is held by a receptacle of the winding machine by means of at least one carriage along at least a guide of the winding machine is arranged movable.
    The invention is characterized in that the carriage is adapted to move from a winding position to a storage position in which the finished cotton roll a recording of a transport device can be handed over.
    In contrast to the prior art is thus completely dispensed with an additional lifting / pivoting device for the transfer of the lap roll on a trolley. The machine can thus be built much shorter. The fact that the previous existing components can be used unchanged to transport the lap in one operation from the winding position to a storage position for transfer to a receptacle of a transport device, an adaptation to different heights of trolley or combers is not necessary.
    Preferably, the storage position is above the recording of the transport device, so that the lap roll can fall into the receptacle of the transport device. The transport device can be arranged closer to the winding machine, which due to the height difference between the recording of the transport device and the storage position, a height adjustment is unnecessary. It is only necessary to make the recording of the transport device or the support for the lap roll over a large area, so that the lap roll is not damaged due to the drop height. An example of this is disclosed in DE 10 2012 013 217 A1. Alternatively, the lap roll may also be received by two or three spaced apart rods having a corresponding bearing surface. In a further alternative, the lap roll can also be taken up by a shell, for example made of sheet metal.
    Further advantageous embodiments will become apparent from the features of the dependent claims.
    Advantageously, the storage position is above the winding position, so that with a small height difference of the lap roll can be dropped into the receptacle of a transport device. But it can also be located laterally from the recording of the transport device, in which the lap roll is deposited from the storage position on a ramp, and rolls by its own momentum in the recording of the transport device.
    In an advantageous embodiment, the winding unit is formed from at least two winding rollers. By a separate drive for each winding roller, which can be controlled individually, a delay can be set in the production of the lap roll, which minimizes the formation of bubbles.
    Particularly preferably, the receptacle is formed by two winding plates that hold the winding tube clamped at their end faces. The reel discs thus form a lateral boundary for the fiber slivers to be wound up.
    In another embodiment, in each case a reel disc may be arranged on a separate carriage, which are arranged on both sides of the machine housing. The winding machine thus has on each side a separate carriage with a reel disc, which can be moved back and forth to each other. The reel discs can thus be moved back and forth in the direction of the sleeves to accommodate the winding tube at the beginning of the winding process, and to move the finished winding without intermediate units in a storage position. In this case, the reel disc can be moved by means of the carriage along the guide, without the wadding must be passed to other units or components.
    In order to minimize the height difference between the storage position and the inclusion of a trolley, move the carriage along the guide in a travel angle (a), the maximum 60 ° to the ground, preferably a maximum of 45 ° to the ground. Over a low travel angle (a) of the carriage, the height difference between the storage position and the recording of the transport device can be reduced.
    A further improvement can be achieved, in which the carriage is arranged pivotably at least in the storage position. Thus, the height difference can be further reduced and the lap roll is transferred from such a small height in the recording of the transport device that damage to the cotton is excluded. A structurally simple design results when the carriage is arranged rotatable or pivotable about the lower winding roller. The entire mechanism connected to the carriage can be pivoted with it.
    For efficient use of the winding machine, at least one carriage having an opening for the lateral introduction of a winding tube in the winding machine, so that they can be operated automatically with a large supply of cores. Furthermore, it is much safer for the operator if you no longer need to reach into the machine when feeding the cores.
    The inventive method for operating a winding machine is specified in claim 11. At the beginning of the winding process, the winding tube is brought by the recording of the winding machine in angular position, generates the lap roll and transported the finished cotton roll in a storage position, without the finished cotton roll over other components must be refixed or transported to compensate for differences in height.
    The invention will be explained in more detail with reference to an embodiment. It shows:
    Fig. 1: a schematic representation of a winding machine;
    2 shows a further illustration of the winding machine according to the invention;
    3 shows a further variant of the winding machine according to the invention;
    4 shows a further variant of the winding machine according to the invention.
    In Fig. 1, a winding machine 1 is shown, as used for example in Kämmereivorbereitung in the textile industry. Several slivers 3, which may consist of natural or synthetic fibers are fed via cans of the winding machine 1 and evened out in a drafting system, not shown. The slivers 3 are further passed over an inlet region 2 to a plurality of pressure rollers 4a-4c, which guide the slivers 3 in the catchment area between two winding rollers 5a, 5b and a winding tube 6 for producing a lap roll. In or on the inlet region 2, a supercharger 8 may be arranged, which makes the sliver 3 uniform. Not shown are arranged in the inlet region 2 table calender, arranged in front of the table calender drafting and arranged in front of the winding machine 1 gate. Alternatively, the lap roll can also be produced within an endlessly circulating belt or between one or two winding rollers and a circulating belt.
    In Fig. 2, a lap roll 15 'has already been stored on a transport device 20. In preparation, the sliver 3 between the pressure rollers 4b and 4c was torn off by further rotating the winding rollers 5a and 5b and, for example, stopping the pressure rollers 4b and 4c very quickly. Alternatively, a tearing of the sliver 3 is also possible between the pressure rollers 4c and the winding roller 5a. Further, one of two slides 10 can be seen here, which are obliquely movable along a guide 12 arranged on both sides of the machine housing. The carriage 10 is / are moved along the guide 12 by means of at least one cylinder 13, for example a pneumatic cylinder. Each carriage 10 has its own reel disc 9, which are movable toward or away from each other and thereby can hold the winding tube 6 by clamping. At the beginning of the winding process, a new winding tube 6 is placed laterally through the opening 11 in the gusset between the winding rollers 5a, 5b. Alternatively, the winding tube 6 can be placed through another machine opening in the gusset between the winding rollers 5a, 5b. The reel disc 9 move with the carriage 10 obliquely down in working position and clamp the
    Winding sleeve 6 a. New sliver 3 is introduced via the pressure rollers 4a, 4b, 4c in the gusset between the winding rollers 5a, 5b and the winding tube 6, so that after the winding tube 6 was clamped by the winding plates 9, the winding process by rotating the winding rollers 5a, 5b start can, which represents the beginning of the winding position, which moves with the outer diameter of the cotton roll 15 to be formed counter to the pulling direction Z. During the winding process, the cylinder 13 pulls the carriage 10 along the guide 12 in the pulling direction Z, so as to build up a static winding pressure or a dynamic winding pressure corresponding to the winding quality to be achieved. In this case, the lap roll 15, the winding tube 6 is clamped by the reel disc 9, pulled against the winding rollers 5a, 5b. Alternatively, the lap roll can also be formed exclusively by a band or a band with a roller.
    After a predetermined length of for example 300 to 400 m, the slivers 3 are torn off in the region of the pressure rollers 4a, 4b, 4c and the winding roller 5a. The lap roll 15 is further held by the reel disc 9, which pinch the winding tube 6. The carriage 10 moves with the reel disks 9 and the lap roll 15 from the gusset of the winding rollers 5a, 5b along the guide 12 in storage direction A in a storage position, which is located above a receptacle of a transport device 20. In this storage position, the winding plates 9 move apart and allow the lap roll 15 fall into a receptacle of the transport device 20.
    About the side opening 11, the next winding tube 6 is inserted into the gusset of the winding rollers 5a, 5b. The carriage 10 moves back in the pulling direction and clamps the winding tube 6 between the reel disc 9, so that the next lap roll can be produced.
    Thus, the drop height of the lap roll 15 is minimized, is provided in a preferred embodiment, the travel angle α of the carriage 10 along the guide 12 to keep as small as possible, preferably at an angle to the bottom of 60 ° maximum, more preferably at most 45 °.
    For this purpose, it is also provided to optimize the transport device by, for example, the receptacle is designed as in DE 10 2012 013 217 A1, in which the oriented to the winding machine front pick-up point is located lower than the rear pick-up point.
    According to the embodiment of FIG. 2, the lap roll 15 is stored or dropped in the storage position A on an inclined ramp 16, so that the lap roll 15 rolls with low momentum into the receptacle of the transport device 20. The storage position A can also be located laterally next to the receptacle of the transport device 20. Thus, the length of the carriage 10, the guide 12 and the cylinder 13 can be further shortened because the lap roll 15 no longer needs to be raised approximately vertically above the receiving the transport device 20. It then reaches a small height difference, in which the ramp 16, on which the cotton roll 15 rolls, is inclined to receive the transport device 20. The storage position of the lap roll 15 is then located laterally above the receptacle of the transport device 20th
    In all embodiments, a sensor 17 is arranged in the winding machine 1, which determines whether a free position for the finished lap roll 15 is present on the transport device 20. If the transport device 20 is completely covered by cotton wool 15 ', the finished cotton roll 15 remains between the reel disks 9. The sensor additionally generates a signal for the operating personnel to empty the transport device 20 or exchange it for a new empty transport device 20.
    The transport device 20 may, as in this embodiment, for example, be designed as a litter-bound transport vehicle, which can accommodate 4, 6 or 8 lap roll 15 and a predetermined number of cores 6 and transported between a combing machine and the winding machine 1. The embodiment of FIG. 2 shows the indicated deposited cotton roll 15 in the receptacle of the transport device 20 and above the carriage 10 with the reel disks 9 in the storage position. Alternatively, the transport device 20 may also be designed as a conveyor belt or delivery table of an automatic conveyor.
    In the embodiment of FIG. 3, the carriage 10 is arranged with the guide 12, not shown, and the cylinder 13 including the winding roller 5a in a flat travel angle α ~ 30 °, whereby the height difference for storage of the lap roll 15 has been significantly reduced. In this case, the entire device, comprising the carriage 10 with the guide 12, the winding plates 9 and the cylinders 13 including the winding roller 5a was rotated about the center of the winding roller 5b.
    In the embodiment of Fig. 4, the carriage 10 has been shortened even further, since here the travel angle to α ~ 20 ° was further reduced. The carriage 10 with the winding plates 9 and the guide 12 is rotatably disposed about the center of the winding roller 5b. In the winding position of the carriage 10 may be arranged, for example, at a travel angle avon 45 ° and the lap roll be generated. Subsequently, the carriage 10 can be pivoted into a storage position with an angle α of, for example, 20 °, whereby the height difference for storage of the lap roll is further reduced. The result is a short-built and extremely compact winding machine that allows transfer of the lap roll on a trolley without an additional lifting / pivoting device.
