Definitions

  • the present invention relates to a method for operating a textile machine, in particular a textile machine producing cross-wound bobbins, most particularly an open-end spinning machine, with a large number of similar work stations, with the help of the work stations during normal operation of the same yarn being produced or rewound from a delivery bobbin to a receiver bobbin and whereby a large number of workstations are started after these workstations are stopped and thus put into normal operation.
  • the invention relates to a textile machine, in particular a textile machine producing cross-wound bobbins, most particularly an open-end spinning machine, with a large number of similar work stations for producing yarn or for rewinding yarn from a delivery bobbin to a receiver bobbin.
  • the EP 3 144 418 A1 proposes to make different control programs available to the workplaces that process different yarn lots. All workplaces that produce the same yarn form a group, for which their own tax data is then made available. The document deals with how this tax data can be stored and selected. However, the document does not provide any information about a quick start to the jobs.
  • the EP 3 168 179 A1 It has already been proposed that the workstations be started successively, with the switch-on pulse for the workstations following the first workstation being delayed by a certain minimum period of time. If all the conditions required to start the workstations are not met, the switch-on pulses are additionally delayed.
  • the object of the present invention is therefore to propose a method for operating a textile machine and a textile machine that enable a large number of jobs to be started quickly, but are simple and uncomplicated.
  • the task is solved by a method for operating a textile machine and a textile machine with the features of the independent claims.
  • a method for operating a textile machine with a large number of similar workstations is proposed.
  • this can be any type of textile machine, as long as it has a large number of similar workstations, but in particular a textile machine that produces cheeses.
  • an open-end spinning machine or an air-jet spinning machine should be mentioned as possible textile machines.
  • the workstations produce yarn during normal operation (spinning machines) or wind yarn from a delivery spool to a receiving spool (winding machines).
  • spinning machines spinning machines
  • wind yarn from a delivery spool to a receiving spool (winding machines).
  • the large number of workstations is divided into groups of workstations and the groups of workstations are started at a time offset from one another. Due to the time delay when starting, the textile machine's resources are also required at different times, so that the available resources are sufficient to start the individual groups of workstations one after the other. It is not necessary that one group of workstations has already started normal operation when the next group of workstations starts; Rather, a small time delay is usually sufficient. This procedure is both simple and straightforward and allows a wide range of jobs to be started quickly.
  • a group of workstations can, for example, comprise fewer than 10 workstations, preferably less than 5 workstations (e.g. 2 workstations).
  • the time delay between the start of successive groups of workstations is a predeterminable waiting time. It is conceivable that the waiting time is specified by the manufacturer of the textile machine, or that the textile machine's operating personnel can adjust this waiting time. Since the start process of the individual workstations and thus the consumption of resources is essentially the same, a predeterminable waiting time allows the workstations to be started quickly using a very simple procedure.
  • the waiting time can preferably be less than 5 s (seconds), particularly preferably less than 1 s.
  • the time delay between the start of successive groups of workstations is determined depending on the status data of the textile machine. While there is a certain waiting time when starting the jobs with a predetermined waiting time Safety reserve of resources must be maintained, it is possible to reduce the required safety reserve by determining the status data of the textile machine and thus achieve an even faster start of the individual groups of workstations.
  • workstations are divided into predeterminable groups of workstations.
  • Physically connected workstations are suitable groups of workstations, for example the workstations of a section or a section page.
  • the predetermined groups of workstations make it very easy to carry out the process.
  • the large number of workstations is divided into groups of workstations, which are determined depending on the status data of the textile machine. For example, it is possible to create groups of workstations of approximately the same size, even if only a few workstations have to be started from one section and almost all workstations from another section. Depending on the resources available, the size of the groups can also be adjusted, with the fewer resources available, the smaller the size of the group. This somewhat more complex procedure leads to an even quicker start of the jobs.
  • groups of workstations next to each other can also be started one after the other.
  • groups of workstations that are as far apart as possible can be started one after the other. In the latter case The heating that occurs when starting work is better distributed across the textile machine. A predeterminable sequence for starting the groups of workstations always leads to a very simple procedure for operating the textile machine.
  • the order in which the groups of workstations are started is determined depending on the status data of the textile machine. This is particularly advantageous if the groups of jobs can be specified and some groups contain many jobs to be started and other groups contain few jobs. Then, by cleverly choosing the order in which the groups start, the available resources can be optimally utilized.
  • the status data includes resources of the textile machine, in particular energy, compressed air and/or negative pressure.
  • parameters of the spun or spooled yarn also count.
  • the resources available are often the limiting factor for quickly starting a large number of jobs. Precise knowledge of the resources available but also of the resources already used is therefore essential for optimal use of resources. Even if the spun or spooled yarn has different properties, for example a different thickness, this leads, for example, to different durations of the starting process and/or to a different consumption of resources. Consequently, knowledge of the parameters of the spun or spooled yarn leads to a faster start of the textile machine's workstations.
  • a textile machine with a large number of similar work stations for producing yarn or for rewinding yarn from a delivery spool to a receiver spool is proposed.
  • the textile machine is therefore a spinning or winding machine, in particular a textile machine that produces cross-wound bobbins, and in particular about an open-end spinning machine.
  • Other textile machines with a large number of similar workstations, such as air-jet spinning machines, are also included in the invention.
  • the textile machine has control means which are designed to operate the textile machine according to one or more of the preceding claims.
  • control means which are designed to operate the textile machine according to one or more of the preceding claims.
  • the large number of workstations are divided into groups of workstations and the groups of workstations are started at a time offset from one another. This results in simple but efficient operation of the textile machine.
  • control means are one or more central control units.
  • the central control unit brings together the information necessary for operating the textile machine, which enables the textile machine to be operated in the best possible way.
  • the textile machine has sensors and/or measuring devices for recording status data of the textile machine.
  • the sensors and/or measuring devices are preferably connected to the control means. This means that the status data of the textile machine can be easily transmitted to the control means.
  • the textile machine is operated according to the previous description and is designed according to the previous description, whereby the features mentioned can be present individually or in any combination.
  • Figure 1 shows a schematic top view of a textile machine 1 according to the invention with a large number of similar workstations 2, of which only some are provided with a reference number for the sake of clarity.
  • the textile machine 1 can be any textile machine 1 that has a large number of similar workstations 2, in particular a spinning or winding machine. Particularly worth mentioning are textile machines 1 that produce cross-wound bobbins, and in particular open-end spinning machines and air-jet spinning machines.
  • the textile machine 1 has a machine head 3, which includes a central control unit 4.
  • a central control unit 4 is an alternative embodiment that operates the textile machine 1 with decentralized control means instead of the central control unit 4.
  • the machine head 3 supplies the workstations 2 with electrical energy or compressed air via power cables 5 and compressed air pipes 6. Other resources, such as negative pressure, may also be required by the workstations 2.
  • the workstations 2 are first divided into groups 7 of workstations 2.
  • the different groups were designated here as 7.1, 7.2, etc.
  • a group 7 of workstations 2 consists of two workstations 2, but a higher number of workstations 2 per group 7 is also conceivable and it is also conceivable that the number of workstations 2 per group 7 is not the same for all groups 7 is.
  • workstations 2 assigned to groups 7.1 to 7,100 are now to be started, workstations 2 in group 7.1 are started first. Workstations 2 of group 7.2 are then started with a time offset from workstations 2 in group 7.1. Due to this time offset, not all resources are required at the same time, so that a quick start of all workstations 2 is possible with the help of the time offset.
  • the workstations 2 were divided into groups 7 of workstations 2, which were determined depending on the status data of the textile machine.
  • the respective group 7.1, 7.2, etc., to which workplace 2 was assigned, is in the respective workplace 2 noted.
  • Workstations 2 without a number in group 7 do not require a start, for example because they are already running in normal operation or have an error that must be corrected before a start.
  • status data that can influence the assignment of workstations 2 to groups 7 are, for example, the resources of the textile machine 1 and/or parameters of the spun or spooled yarn. By including this status data, workstations 2 can be assigned to groups 7 in such a way that workstations 2 can be started even faster.
  • the number of workstations 2 per group 7 can also be determined, as well as the waiting time between the start of a group 7 and the subsequent group 7.
  • the method according to the invention which is simple and uncomplicated, enables workstations 2 to be started quickly after these workstations 2 have stopped.
