Definitions
- the invention relates to a method for operating an automatic cheese winder which has a plurality of work stations and a cop and tube transport system in which spinning cops rotate, which are arranged on transport plates which have an information carrier on which the current winding status of the spinning cops is stored, and the bobbin and tube transport system is equipped with at least one bobbin preparation station, a tube cleaning device and a manual preparation device, with the manual preparation device temporarily storing spinning bobbins that were not properly prepared for the winding process in the bobbin preparation station and alarm bobbins, i.e. spinning bobbins that exceed a limit number have yarn defects, can be stored.
- the bobbin and tube transport system of the automatic package winder then supplies the work stations of the automatic package winder with fresh spinning bobbins and ensures that empty tubes that have been spooled off are transported back to the ring spinning machine.
- the bobbin and tube transport system of the automatic cheese winder usually has different transport routes and processing devices for distributing or processing the fresh material delivered by the ring spinning machine spinning cops up.
- such bobbin and tube transport systems each have a machine-long bobbin feed section, a machine-long bobbin discharge section and a reversibly drivable storage section, with the bobbin feed section and the bobbin discharge section often having a connecting section at the end are connected.
- the storage section is connected to the core discharge section via so-called transverse transport sections, which run in the area of the work stations.
- a so-called bobbin preparation station is installed in an area between the bobbin feed line and the storage line, in which the fresh spinning bobbins delivered by the ring spinning machine are prepared for a subsequent rewinding process, which is carried out at the work stations of the automatic cheese winder.
- Spinning bobbins that could be properly prepared in the bobbin preparation station are then ejected onto the storage line, while spinning bobbins that failed to create a proper winding are fed back into the bobbin feed line and then transported to a manual preparation device.
- the correctly prepared spinning cops discharged onto the storage section are then distributed to the numerous transverse transport sections, each of which has an unwinding position which is arranged below the bobbin housing of the work stations, and wound there into large-volume cross-wound bobbins.
- the thread running off the spinning cop is also scanned by a thread monitor, which detects thread faults such as thick or thin points and ensures that these faults are cleaned out immediately.
- the spinning cop is usually completely unwound, that is, the cop tube arranged on the transport plate is completely empty.
- the cop tube at the end of the rewinding process still has a residual thread quantity that falls below a predetermined minimum quantity.
- cop tubes are then discharged onto the tube return section and conveyed in the direction of the ring spinning machine, with cop tubes that still have a residual amount of thread being sent through a tube cleaner and cleaned by it.
- Such a faulty spinning cop which is also referred to in professional circles as an alarm cop, should then be removed from the cop and tube transport system of the automatic cheese winder as quickly as possible.
- the spinning cop is therefore often transported to the manual preparation facility, where it can be easily handled by the staff, i.e. easily removed.
- alarm bobbins processed in this way represent an unnecessary additional load on the bobbin and tube transport system, which should be avoided if possible.
- a bobbin and tube transport system has already been developed for an automatic cheese winder, the manual preparation device of which is equipped with a specially designed storage disk.
- This cop and tube transport system described in DE 102017 123777 A1 has a storage disk that can be controlled in a defined manner and has pocket-shaped recesses for accommodating residual bobbins, unprepared spinning bobbins or alarm bobbins.
- the pocket-shaped recesses are designed differently and each designed to accommodate a specific type of spinning cop.
- the transport plates of the spinning cops are, as is known, equipped with electronic information carriers on which it is noted which winding state the present spinning cop has.
- a reading device which evaluates the data on the information carrier and which is connected to the control device of the automatic cheese winder ensures that each of the spinning cops is guided into the associated pocket-shaped recess of the storage disc according to its winding state.
- this known device since the storage disc stores all types of spinning cops at the same time, this known device has the disadvantage that the capacity of the device is relatively limited. This means that the operating personnel must check at relatively short time intervals whether the storage disk is already full and, if necessary, take action.
- the object of the invention is to develop a method for operating an automatic cheese winder, in which, on the one hand, alarm bobbins can be reliably detected and removed, and, on the other hand, it is ensured that the manual preparation device has optimal receiving conditions for the spinning bobbins for a reasonable period of time given are.
- the manual preparation device can be operated in at least two operating modes, with only full bobbins being fed into the manual preparation device in the first operating mode and only alarm bobbins being fed into the second operating mode.
- the method according to the invention has the particular advantage that with a manual preparation device that can be operated in two operating modes, it can be ensured in a simple manner that only one type of spinning cops is stored in the manual preparation device.
- the operating personnel can manually post-treat spinning bobbins that could not be properly prepared in the bobbin preparation station, that is, equip the spinning bobbins with a proper overwinding. However, if there are alarm cops in the manual preparation facility, these can be sorted out immediately.
- the automatic cheese winder by means of call lamps arranged on the automatic cheese winder, which are connected to the machine control of the automatic cheese winder, it is indicated that the manual preparation device is full.
- the information on the control unit of the automatic cheese winder can also display the message: "Manual preparation device full”.
- the aforementioned display and signaling devices ensure that the operating personnel are always informed quickly when the manual preparation device is full and manual use is necessary. Consequently, the operating personnel can promptly ensure by appropriate actions that the manual preparation device is fully operational again.
- a further advantage of the method according to the invention can be seen in the fact that the second operating mode can only be activated if it is ensured that sufficient alarm bobbins are circulating in the bobbin and tube transport system. This means, at the time of the intended activation of the second operating mode, so many alarm bobbins must be circulating in the cop and tube transport system that the manual preparation device can be filled within a relatively short time. In this way it can be reliably avoided that the cop and tube transport system is unnecessarily burdened by the manual preparation device working in an operating mode in which the manual preparation device cannot be filled in the foreseeable future.
- the figure shows a schematic plan view of a bobbin and tube transport system 1 of a cheese winder, in which the method according to the invention is used.
- transport sections 2 and 3 are often connected to such cop and tube transport systems 1, via which the cop and tube transport system 1 is connected, for example, to a (not shown) transport system of a ring spinning machine upstream in the production process.
- Fresh, unprepared spinning cops 8 produced on the ring spinning machine are delivered via the transport path 2 , which are arranged in a vertical orientation on transport plates 10 , each of which is equipped with an information carrier 9 .
- the bobbin and tube transport system 1 itself has numerous other transport sections, for example a machine-long bobbin feed section 4 and a machine-long bobbin return section 5 as well as a reversibly drivable storage section 6.
- the cop feed section 4 and the sleeve return section 5 are connected at the ends via a connecting section 12 and 13, respectively.
- a plurality of so-called transverse transport sections 7 branch off from the reversibly drivable storage section 6 , via which the storage section 6 is connected to the sleeve return section 5 .
- the transverse transport sections 7 each run below one of the work stations of the automatic cheese winder and have a so-called unwinding position for the spinning cops 8 .
- the spinning cop 8 to be rewound is positioned and wound onto a cross-wound bobbin stored in the winding device of the work station.
- the bobbin and tube transport system 1 of the automatic cheese winder is equipped with a so-called preparation section 17 which is connected to the bobbin feed section 4 via connecting sections 19, 20 and to the storage section 6 via a connecting section 21.
- the cop and sleeve transport system 1 also has a transport section 22 which is arranged between the sleeve return section 5 and the cop feed section 4 and from which a transport section 23 branches off.
- the cop and tube transport system 1 is also equipped with various cop handling or treatment devices, such as a cop preparation station 14, a tube cleaning device 15 and a manual preparation device 16, and has sensor devices 24A - 24F that communicate with the machine control 25 of the cheese winder in question.
- various cop handling or treatment devices such as a cop preparation station 14, a tube cleaning device 15 and a manual preparation device 16, and has sensor devices 24A - 24F that communicate with the machine control 25 of the cheese winder in question.
- the machine control 25 then ensures that corresponding points, which are usually arranged behind the sensor devices 24A - 24F in the transport direction and are not shown in the drawing for reasons of clarity, are actuated and the relevant spinning cops 8 are guided properly in the cop and tube transport system 1 .
- a sensor device in the form of a thread monitor 18 is installed at each of the work stations of the automatic cheese winder in an area above the unwinding position for the spinning cops, which is also connected to the machine control 25 of the automatic cheese winder.
- the thread monitor 18 scans the thread running off the spinning cop 8 for thread defects and ensures, among other things, that thread defects, for example thick or thin places, are cleaned out immediately.
- this spinning cop is marked as an alarm cop and immediately ejected from the work site.
- fresh, unprepared spinning cops 8 produced on the ring spinning machine are fed into the cop and tube transport system 1 of the automatic cheese winder via the transport route 2 and transported in the transport direction T on the cop feed route 4 .
- the fresh spinning cops 8 first reach the area of a sensor device 24A, which uses the data on the information carrier 9 arranged on the transport plate 10 to recognize that the arriving spinning cop is a fresh spinning cop 8 that has not yet been prepared.
- the sensor device 24A then ensures that the fresh, unprepared spinning cop 8 is diverted via the connection section 19 to the preparation section 17 and properly prepared in the cop preparation station 14 for a subsequent rewinding process.
- the spinning cop processed in the cop preparation station 14 is then checked by a sensor device 24B arranged behind the cop preparation station 14 and the processing status of the spinning cop is read on the information carrier 9 of the transport plate 10 .
- Spinning cops which could not be properly prepared in the cop preparation station 14, which the sensor device 24B detects, are marked as spinning cops 8B and are sent back to the cop feed section 4 via the connection section 20.
- the spinning cop 8B is transported further via the cop feed section 4, the connecting section 13 and the tube return section 5 and finally reaches the area of the sensor device 24C, which ensures that the spinning cop 8B is transported via the transport sections 22, 23 to the manual preparation device 16, where it is temporarily stored is saved and awaits manual post-processing by the operating personnel.
- the correctly prepared spinning cops 8A discharged onto the storage section 6 are distributed over the transverse transport sections 7 and rewound to form cheeses at the unwinding points of the work stations 11 of the automatic cheese winder.
- the thread running off the spinning cop 8A is also monitored for thread defects, which are cleaned up immediately.
- the spinning cop 8A to be unwound is completely unwound at the work site, which is recorded on the information carrier 9 of the transport plate 10, that is, the information carrier 9 is given the identification 8C, for example.
- the empty tube arranged on the transport plate 10 is ejected onto the tube return path 5 and transported by it in the direction of the ring spinning machine.
- Sensor devices 24C and 24F recognize that it is an empty tube 8C and ensure that the empty tube 8C is transferred directly to the transport path 3 .
- Spinning bobbins that could not be completely processed in work stations 11 and only have a residual value that is below a minimum are also marked.
- spinning bobbins identified as remaining bobbins 8D, are also discharged onto the bobbin return path 5 and conveyed to a bobbin cleaning device 15, where their bobbins are cleaned.
- the cleaned empty tube is then also transferred to the transport section 3 and transported back to the ring spinning machine.
- spinning bobbins that still have a residual value worth unwinding, for which the rewinding process can no longer be started properly at the work site, for example due to an undetectable overwinding, are marked as residual bobbins 8E and are also ejected onto the tube return line 5.
- Residual bobbins 8E are either transported via the connecting route 12 to the cop feed route 4 and prepared again in the cop preparation station 14, or the remaining bobbins 8E are transported via the transport routes 22, 23 to the manual preparation device 16, where they are manually prepared.
- the yarn coming out of the spinning cop 8A is during of the rewinding process in the work station 11 is monitored by a thread monitor 18 for thread defects.
- the spinning cop is identified as an alarm cop 8F and immediately ejected onto the tube return path 5 .
- alarm bobbins 8F Since such alarm bobbins 8F must be removed from the cop and tube transport system 1, alarm bobbins 8F are also stored in the manual preparation facility 16 as soon as possible, from where they can be removed by the operating personnel.
- the invention provides that the manual preparation device 16 can be operated in two operating modes. This means that in a first operating mode A only spinning cops 8B are stored in the manual preparation device 16, which are finally manually provided with an overwinding by the operating personnel, while in the second operating mode B only alarm cops 8F are fed into the manual preparation device 16, which the operating personnel then be removed.
- the operating mode is clearly displayed on the operating unit 26 of the automatic cheese winder by means of a pictogram 27 .
- the operating personnel can clearly see whether, for example, operating mode A is currently running, i.e. that the spinning cops entering the manual preparation device 16 are spinning cops 8B that have to be prepared manually, or whether operating mode B is currently pending, enter the hand preparation device 16 at the alarm cops 8F, which should be removed from the cop and tube transport system 1.
- call lamps 28 arranged on the automatic cheese winder which are connected to the machine control 25 and/or an information device on the operating unit 26 of the automatic cheese winder, display a corresponding message when the manual preparation device 16 is full and the operating personnel must take action.
- the operator can temporarily switch from operating mode A, in which unprepared spinning cops 8B enter the hand preparation device 16, to operating mode B, in which alarm cops 8F are collected in the hand preparation device 16.
- the invention also provides that operating mode B is only activated then can, if it is ensured that in the bobbin and tube transport system 1 of the automatic cheese winder enough alarm bobbins 8F circulate. This means that operating mode B can only be activated if there are sufficient alarm pods 8F to be able to fill the manual preparation device 16 with alarm pods 8F within an acceptable period of time.
