Description
Technical Field
The invention relates to a maintenance vehicle for automatically supplying a spinning position of a spinning machine for manufacturing a yarn bobbin, comprising an auxiliary yarn bobbin with an auxiliary yarn for receiving the auxiliary yarn after the yarn bobbin is replaced and an auxiliary yarn guiding mechanism for guiding the auxiliary yarn to the spinning position of the spinning machine. The invention also relates to a method for operating a maintenance vehicle for automatically supplying a plurality of spinning positions of a spinning machine for producing yarn bobbins.
Background
A number of designs of maintenance vehicles of the type mentioned in the introduction are known from the prior art. Thus, DE19939801a1 discloses a service unit for automatically supplying spinning positions of an open-end rotor spinning machine. The maintenance unit has a mechanism for engaging the yarn end to the fiber ring rotating with the spinning rotor, a yarn drawing mechanism, a yarn transfer component and a mechanism for monitoring the transfer of the yarn. Furthermore, a sensor device, preferably in the form of an optical scanner, is arranged in the region of the yarn transfer part, so that a signal is generated by the sensor device when the yarn transfer part is first in the yarn transfer position and the yarn of the reciprocating yarn guide to be transferred to the spinning position has a sufficiently high yarn tension.
The service trolley of the spinning machine is especially provided for placing a new bobbin into a bobbin creel of one of a plurality of spinning positions of the spinning machine after a full bobbin is placed on the bobbin conveyor belt. Since the new empty bobbin still has no yarn, the splicing is carried out with auxiliary yarn from an auxiliary yarn bobbin of the maintenance vehicle. However, if the auxiliary yarn bobbin is empty, the yarn splicing process is not performed. The respective spinning position is kept in the same position until the operator places a new full auxiliary yarn bobbin in the maintenance vehicle.
Disclosure of Invention
The invention is based on the object of providing a maintenance vehicle and a method by means of which the number and duration of interruptions in the operation of a spinning machine due to empty auxiliary yarn bobbins of the maintenance vehicle can be reduced.
The invention relates to a maintenance vehicle for automatically supplying a spinning station of a spinning machine for producing a yarn bobbin, comprising an auxiliary yarn bobbin for receiving an auxiliary yarn after the yarn bobbin is replaced and an auxiliary yarn guide for supplying the auxiliary yarn to the spinning station of the spinning machine or to a newly delivered empty bobbin, wherein at least one sensor for detecting the state of the auxiliary yarn bobbin is arranged on the maintenance vehicle in order to be able to distinguish between an empty auxiliary yarn bobbin state and an auxiliary yarn bobbin state with the auxiliary yarn.
In the method according to the invention for automatically supplying a service vehicle for operating a spinning station of a plurality of spinning machines for producing yarn bobbins, the state of an auxiliary yarn bobbin of the service vehicle is first automatically detected by means of a sensor, and then an alarm signal is generated and transmitted when an empty or idle auxiliary yarn bobbin is detected by means of the sensor.
The inventors have also found that in the prior art service vehicle the operator cannot find out whether the auxiliary yarn bobbin is running empty or even empty shortly. The operator must therefore regularly visit the maintenance vehicle to check it, wherein in spinning machines with a large number of spinning positions the maintenance vehicle can be currently located at a remote location and it therefore takes a relatively long time. If an empty auxiliary yarn bobbin is not replaced by a new auxiliary yarn bobbin in due time, all the spinning positions on which bobbin replacement has already been carried out cannot be spliced again, so that the number of spinning positions of the spinning machine which are in operation is always reduced.
The inventors have also found that it is advantageous to inform the operator of the spinning machine when or in which maintenance vehicle there is an empty or idle auxiliary yarn bobbin in good time. The service vehicle according to the invention and the method according to the invention therefore permit, in a very advantageous manner, a quick and simple recognition of when an auxiliary yarn bobbin has to be replaced on the service vehicle, so that long-term operational interruptions can be prevented.
The spinning machine can be any spinning machine for producing yarns, yarns or twists. The spinning machine is preferably an air spinning machine or a rotor spinning machine, particularly preferably an open-end rotor spinning machine. The spinning machine has a plurality of spinning positions for producing the yarn, which are preferably designed in the form of a spinning box, more preferably each having a rotor. It is also preferred that the yarn produced at each of the spinning positions is wound onto a bobbin or a bobbin in the spinning position or on the spinning machine immediately thereafter. In principle, it can be any bobbin, but here it is preferred that the spinning machine produces a cross-wound bobbin.
During the operation of the spinning machine, the maintenance vehicle is provided for supplying individual spinning positions which are preferably identical to one another. For this purpose, the respective spinning position preferably requires a maintenance vehicle by means of data telegrams. The service trolley is in place before the spinning station and requires, for example, a new empty bobbin for bobbin replacement. The wound bobbin, in particular a cross-wound bobbin, can then be placed on a bobbin removal belt, and the maintenance vehicle preferably places a new bobbin into a creel of the spinning station. The yarn joining is carried out by using an auxiliary yarn of the maintenance vehicle. After the yarn joining, the auxiliary yarn is sucked off and a reserve yarn is wound off with the just spun yarn or yarn, only then does the normal winding process begin and the spinning station can take over the yarn inspection.
The maintenance vehicle automatically supplies a large number of spinning places of a spinning machine, in particular an open-end rotor spinning machine, i.e. the maintenance vehicle intervenes without the request or instruction of an operator when a maintenance vehicle is required at one of said spinning places. This is the case, for example, when a yarn break occurs at one of the spinning positions or when a new bobbin has reached its specified diameter at one of the spinning positions and has to be replaced by an empty bobbin.
The maintenance vehicle can be of essentially any design and can have any function. Preferably, the maintenance vehicle is a change cleaning vehicle and/or a yarn joining vehicle. In addition to the auxiliary yarn bobbin and the auxiliary yarn guide, the maintenance vehicle preferably has a mechanism which allows an orderly splicing of the yarn ends or auxiliary yarns retrieved from the cross-wound bobbin. The maintenance vehicle can also have, for example, means for engaging the thread end with a fibre ring rotating with the spinning rotor, thread take-off means, thread transfer means and/or means for monitoring the thread transfer means.
The bobbin of auxiliary yarn of the service vehicle can be essentially any bobbin which can supply auxiliary yarn. The auxiliary yarn guide device is provided for reliably guiding the auxiliary yarn unwound from the auxiliary yarn bobbin to a maintenance vehicle position, in which a spinning position of the spinning machine is prepared for spinning the yarn on a new bobbin or another yarn bobbin by means of the maintenance vehicle. For this purpose, the auxiliary thread guide can be of any design, wherein the auxiliary thread can be guided mechanically and/or pneumatically. The turning of the auxiliary yarn is preferably carried out mechanically, for example on a roll. Alternatively or additionally, the linear and/or curved guidance of the auxiliary yarn is preferably carried out by means of an air flow.
The at least one sensor may be any sensor, by means of which the state of the auxiliary yarn bobbin can be directly detected, in particular directly on the auxiliary yarn bobbin, and/or indirectly, in particular in the yarn guiding region. In this case, the sensor can measure the auxiliary thread essentially purely mechanically, but alternatively has electrical and/or optical and/or acoustic components for measuring the auxiliary thread. The sensor preferably has at least one unit for electronic detection and signal transmission. In particular, the sensor preferably recognizes the state of the auxiliary yarn bobbin in a contactless manner, so that a non-interfering interaction of the sensor with the rotating auxiliary yarn bobbin or the conveyed auxiliary yarn can occur. It is basically possible for the maintenance vehicle to have one or more sensors, wherein a plurality of sensors, in particular a plurality of different sensors, are preferably arranged on the maintenance vehicle. In this case, it is more particularly preferred to arrange a plurality of sensors in the region of the auxiliary yarn bobbin and/or of the auxiliary yarn guide for the auxiliary yarn bobbin.
The state of the auxiliary yarn bobbin is understood to mean, firstly, any parameter of the auxiliary yarn bobbin, by means of which it is possible to determine at least whether additional auxiliary yarn is located on the auxiliary yarn bobbin. For this purpose, the state can relate to the auxiliary yarn itself and/or the amount of auxiliary yarn located on the auxiliary yarn bobbin, but also to other parameters or properties of the auxiliary yarn bobbin, whereby empty auxiliary yarn bobbins and non-empty auxiliary yarn bobbins can be distinguished at least. In principle, therefore, the weight and/or the rotational speed or, in general, the movement of the auxiliary yarn bobbin can also be detected by means of a sensor, since the empty bobbin of the auxiliary yarn bobbin is no longer rotated when it is driven or rotated by the unwound auxiliary yarn during the delivery of the auxiliary yarn.
Thus, according to the invention, the state of the auxiliary yarn bobbin only has to be able to qualitatively indicate whether the auxiliary yarn bobbin is empty or whether auxiliary yarn is still present on the auxiliary yarn bobbin. However, it is preferred that the state of the auxiliary yarn bobbin is detected in such a way that at least one further state can be determined in which only a predetermined small amount of residual auxiliary yarn remains on the auxiliary yarn bobbin. The state is particularly preferably determined such that the amount of auxiliary yarn on the auxiliary yarn bobbin can be specified qualitatively at each operating point.
The automatic detection of the auxiliary yarn bobbin device by means of the sensor means: several measurements with the aid of the sensor need not always be caused by an operator, but are automatically detected continuously or periodically. It is also conceivable that the detection of the state of the auxiliary yarn bobbin takes place only during and/or after the use of the auxiliary yarn, since the amount of auxiliary yarn is not changed when the maintenance vehicle is not currently in use.
Furthermore, according to the invention, an alarm signal is generated and forwarded when an empty or idle auxiliary yarn bobbin is detected, wherein this can take place in the sensor, in a data processing device connected thereto or in a control device of the maintenance vehicle or of the spinning machine.
According to an advantageous development of the maintenance vehicle according to the invention, the sensor is directed at the surface of the yarn wound on the auxiliary yarn bobbin, so that the state of fullness of the auxiliary yarn bobbin can be detected directly in a very simple manner. Preferably, the sensor is a distance measuring sensor, in particular a laser distance measuring sensor, which is aligned, particularly preferably perpendicularly to the central longitudinal or rotational axis of the auxiliary yarn bobbin, with the surface of the yarn wound on the auxiliary yarn bobbin. The sensor thus not only distinguishes the qualitative state of an empty auxiliary yarn bobbin from the qualitative state of an auxiliary yarn bobbin with auxiliary yarn, but also allows a quantitative indication of the full state, so that a minimum amount of auxiliary yarn below the auxiliary yarn bobbin can also be detected. Alternatively, the sensor may be any other ranging sensor such as an ultrasonic ranging sensor. In addition to this sensor, other identical or different sensors for detecting the state of the auxiliary thread can also be arranged on the maintenance vehicle.
In a further preferred embodiment of the inventive service trolley, the sensor or one of the sensors is/are a light barrier, which is preferably arranged parallel to and/or spaced apart from the central longitudinal or rotational axis of the auxiliary yarn bobbin, so that the light barrier is closed when the minimum auxiliary yarn residual quantity is undershot, as a result of which it can be detected in a very simple manner that not only is the auxiliary yarn bobbin empty, but also that the auxiliary yarn bobbin has undershot the minimum auxiliary yarn quantity and should therefore be replaced in time, in order to completely prevent an interruption in the operation of the spinning machine. A light barrier is generally a sensor device in which a first sensor unit emits a signal, preferably an optical signal, which can be received by a second sensor unit opposite the first sensor unit. If no object is located in the area between the two sensor units, the grating is switched off. If it is otherwise interrupted by an object, the grating opens.
The auxiliary yarn bobbin is preferably arranged in the raster or between two sensor parts of the raster in such a way that the raster is kept open when the auxiliary yarn bobbin is full of yarn, and the raster is only closed below a minimum auxiliary yarn residual determined by the distance of the raster from the central longitudinal axis or the surface of an empty auxiliary yarn bobbin.
In a preferred embodiment of the inventive service vehicle, the sensor or one of the sensors is a thread monitor, which is preferably arranged in particular downstream of the auxiliary thread bobbin and/or on the auxiliary thread in the region of the auxiliary thread guide, as a result of which it can be determined in a simple manner whether an auxiliary thread is also provided by the auxiliary thread bobbin. In principle, a thread monitor is a device which is passed at least in regions by the thread to be monitored and which detects the thread, preferably optically or mechanically. In this case, the thread monitor can substantially distinguish between empty and non-empty auxiliary thread bobbins.
In an advantageous development of the maintenance vehicle according to the invention, at least one sensor, preferably all sensors, is connected to a control device of the maintenance vehicle, wherein the control device particularly preferably has an interface for forwarding data signals or alarm signals to at least one terminal. The transfer can take place directly from the control device to the terminal, or via a plurality of stations, for example via a telephone center, signaling devices or signal lights, control systems or consoles, communication centers, etc. Furthermore, the signal transfer can take place in any manner, for example wired or wireless. It is also possible that a part of the multiple transfers or transfers to a plurality of stations can be done electrically or by means of cables one after the other or simultaneously, while in particular another part of the terminal is done wirelessly.
Basically, the terminal can be any technical device which is suitable for displaying signals to the textile machine operator, for example a lamp, an information notification means, an information screen, a smart watch, a telephone and especially a smartphone, a tablet, a portable computer and/or other forms of portable electronics. In particular, the terminal simultaneously allows the operator to feed back to the control device of the maintenance vehicle and/or spinning machine and/or to another person, for example in a communication center or a telephone center or a central operating control or monitoring device.
A preferred embodiment of the method according to the invention provides that a quantitative monitoring of the state of fullness of the auxiliary yarn bobbin is carried out or can be carried out and that the warning signal is generated below a minimum residual amount of auxiliary yarn, so that the operator is advantageously warned before the auxiliary yarn bobbin is completely empty and thus a disruption of operation due to the lack of auxiliary yarn can be completely prevented.
In a further preferred embodiment of the method according to the invention, the warning signal is forwarded to a signal light provided on the spinning machine, in particular on the maintenance vehicle, and/or to a human-machine interface (HMI) or an information notification means, in particular on the spinning machine or on the maintenance vehicle, in order to display a warning message there. Alternatively or additionally, preferably following this, the warning signal is forwarded, in particular by means of a portable terminal, to the control system or to a telephone center (POC) and/or to the spinning machine operator in order to inform the supervisor operator, so that the operator, and thus also the company operating the spinning machine, can advantageously be made aware of the operating state of the maintenance vehicle.

Detailed Description
In a first embodiment of a maintenance vehicle 1 of a free-end rotor spinning machine for producing cross-wound yarn bobbins, as schematically shown in fig. 1a and 1b, an auxiliary yarn bobbin 2 is arranged in the maintenance vehicle 1. The auxiliary thread 3 is guided out of the maintenance vehicle 1 from the auxiliary thread bobbin 2 by means of an auxiliary thread guide 4, wherein the auxiliary thread 3 is deflected in the region of the auxiliary thread guide 4 by means of a deflection roller 9.
In order to be able to determine whether the auxiliary yarn bobbin 2 is empty, a yarn monitor 5c is provided as a sensor 5 in the region of the auxiliary yarn guide 4. The auxiliary yarn 3 passes through a yarn monitor 5c (see fig. 1 a). The thread monitor 5c is connected via a signal line 14 to the control device 10 of the service trolley 1, so that the thread monitor 5c can send a signal to the control device 10 when the auxiliary thread 3 is no longer detected in the thread monitor 5c and the auxiliary thread bobbin 2 is correspondingly empty (see fig. 1 b).
In the control device 10, the signals of the sensors 5 are processed and then first transferred to a signal light or an information reporting means 11 configured as a Human Machine Interface (HMI). In addition, the control system or communication center 12 informs the enterprise operating the spinning machine and, finally, the supervisor obtains information about the required replacement of the auxiliary yarn bobbin 2 by means of the mobile telephone 13.
Alternatively or additionally, as sensor 5, it is also possible to use a light barrier 5b, which is arranged parallel to the central longitudinal axis 7 of the auxiliary yarn bobbin 2, so that, in the case of a full auxiliary yarn bobbin 2, the auxiliary yarn 3 located thereon is arranged between the delivery 8a of the light barrier 5b and the receiving 8b of the light barrier 5b, so that, in the case of a full auxiliary yarn bobbin 2, the light barrier 5b is interrupted (see fig. 2 a). If the auxiliary yarn 3 on the auxiliary yarn bobbin 2 is now consumed step by step, the diameter of the auxiliary yarn bobbin 2 is reduced, so that finally the auxiliary yarn 3 on the auxiliary yarn bobbin 2 is no longer located between the delivery part 8a and the receiving part 8b of the light barrier 5b, so that the light barrier 5b is closed (see fig. 2 b). Accordingly, the spinning machine operator then receives a message that only a small amount of the remaining auxiliary yarn 3 is still on the auxiliary yarn bobbin 2 and that the auxiliary yarn bobbin 2 has to be replaced in order to prevent the spinning machine from being interrupted.
In addition, alternatively or additionally, a laser distance measuring sensor 5a is also used in the maintenance vehicle 1 to quantitatively determine the amount of auxiliary thread 3 located on the auxiliary thread bobbin 2. For this purpose, the laser distance measuring sensor 5a is aligned perpendicular to the central longitudinal axis 7 at the surface 6 of the auxiliary yarn bobbin 2, so that the distance to the surface 6 is measured (see fig. 3a and 3 b). Therefore, the residual amount of the auxiliary yarn 3 can be accurately determined at any time by means of the laser ranging sensor 5 a.
