Definitions
- the invention relates to a method for cleaning a cop tube arranged on a arbor of a movable carrier of a cop and tube transport system, with stripping jaws of a thread stripping device adjustable in the longitudinal axis direction of the arbor along the surface of the cop tube, with the following steps
- the cop and tube transport system required for this generally has a transport belt guided along a guide track, on which the carriers rotate with their vertically arranged arbors.
- the cop tubes are slipped onto the arbors of the carrier and remain on these carriers during the feed, during the unwinding and also as empty tubes during the return.
- the cop and tube transport systems preferably have several transport loops, which lead either to the individual winding stations or to the specific treatment device, such as, for example, cop preparation devices, tube cleaning devices or slip-on devices.
- the specific treatment device such as, for example, cop preparation devices, tube cleaning devices or slip-on devices.
- there are alternative route sections where these are temporarily stored so that they are accessible to the operating personnel.
- the carrier carrying it is transported to the processing station provided, for example to a tube cleaning device or to a cop preparation device.
- a cop usually referred to as a residual cop has a small amount of residual thread, which is generally detected by a tube monitor on the cop that is present in the winding unit.
- bobbins with residual amounts of thread must be freed from the thread arranged on the bobbin so that they can be rewound.
- a residual thread is stripped off the cop tube by means of stripping jaws. If the residual thread quantity exceeds a predetermined size, this can mean that the cleaning process within the tube cleaning device can no longer be carried out, after experience has shown that the stripper jaws of such cops become blocked, which can lead to the entire cop tube being destroyed. If, for example, by means of a tube monitor, a corresponding cop with an excess amount of yarn residue is detected, then this requires the intervention of an operator to clean these cops, as is the case with alarm cops and cops that cannot be prepared.
- the invention is based on the object of providing a device and a method for cleaning a cop tube, by means of which reliable cleaning is ensured even with an increased amount of residual thread.
- the invention solves the problem by a method with the features of claim 1 and a device with the features of claim 6.
- Advantageous developments of Methods according to the invention are set out in dependent claims 2-5.
- the method according to the invention is characterized in that during the stripping process the speed of movement of the stripping jaws is recorded and if the speed falls below a specified minimum, a fault elimination process is carried out in which the stripping jaws, disengaged from the surface of the cop tube, are then moved within the cleaning section in the direction of the The hold-down element is moved into an intermediate position and then placed against the surface of the cop tube again in the intermediate position, after which the wiping process is restarted until the end of the cleaning section is reached, and then the wiping process as a supplementary wiping process in the area of the position of the wiping jaws at the beginning of a previous fault elimination process is repeated to clean the entire cleaning section.
- the control unit via a suitable control unit the speed of movement of the stripper jaws during the cleaning process of the cop tube, i. H. while the stripping jaws are moved over the cleaning section along the surface of the cop tube in the direction of the hold-down element and thereby strip existing thread residues from the cop tube, is monitored and the control unit interrupts the stripping process if the speed falls below a previously set minimum. If the speed of movement of the stripper jaws falls below the minimum speed during the cleaning process, this results in the stripper jaws being blocked due to the thread remnants. As a result, after the stripping process has been interrupted, the stripping jaws are lifted off the cop tube, then adjusted along the cleaning path towards the end of the tube and placed back against the cop tube in an intermediate position, from where the stripping process is then restarted.
- the method according to the invention is based on the finding that, after the shift into the intermediate position, a smaller amount of thread must first be stripped off via the stripping jaws in the direction of the hold-down device, which bake the stripping opposes a lower resistance force, so that there is a higher probability that the remaining, reduced cleaning distance, starting from the intermediate position in the direction of the hold-down device, will be cleaned without a further interruption.
- the wiping jaws are then returned to the position they were in at the beginning of the troubleshooting process, i.e. to the position in which they were previously of the cop sleeve have been lifted.
- the remaining uncleaned portion of the cop tube is cleaned by a supplementary stripping process in the area between the position of the stripping jaws at the time the fault was eliminated and the intermediate position. Reliable cleaning of the remaining cleaning section results from a lower resistance, which results from the cleaning of the cop tube that has already taken place, starting from the previously approached intermediate position up to the end of the cleaning section.
- the method according to the invention thus makes it possible, in addition to cops with an increased amount of residual thread, to also clean those cop tubes which, such as alarm cops or cops that cannot be prepared, have a large amount of thread on their surface which cannot be stripped off in one go.
- Monitoring the movement speed of the stripper jaws in the direction of the hold-down element and interrupting the cleaning process when the speed falls below a previously defined minimum is crucial. This is followed by a displacement of the stripper jaws within the cleaning section into an intermediate position on the cop tube facing towards the hold-down element, from which position the cleaning process is restarted or continued.
- a fault elimination process can be carried out again, in which the scraper jaws are lifted up again and moved to another intermediate position, from where the cleaning process is restarted.
- the first supplementary wiping process takes place, in which the wiping jaws are moved to the position in which they were at the beginning of the previous fault elimination process, so that the cleaning process is then started.
- the number of supplementary wiping processes thus results directly from the number of fault clearance processes carried out during the cleaning, the positions of the scraper jaws being approached step by step, which they had assumed at the beginning of the previous fault clearance process, and then the cleaning process is started. If, during a supplementary stripping process, the movement speed falls below the specified minimum speed again, a fault elimination process takes place again.
- the method according to the invention thus makes it possible to clean the surface of the cop tube in one or more steps until it has been completely removed from thread residues.
- the method according to the invention thus also makes it possible to set the parameters for the bobbins to be fed to the bobbin cleaning on the bobbin monitor in such a way that bobbins and alarm bobbins that cannot be prepared are also fed to the bobbin cleaning, which means that cleaning or preparation to be carried out by the operating personnel can be completely dispensed with.
- the method according to the invention is based on the fact that after an interruption in the stripping process due to the speed falling below a previously defined minimum, a fault elimination process is carried out, during which the cleaning process is interrupted and restarted at a higher point within the cleaning section on the cop tube - in relation to the position of use is from which the remaining amount of thread to be stripped off on the cop tube opposes a lower resistance to the stripping jaws. If, starting from the intermediate position, the minimum speed is again undercut, the fault is eliminated again, during which the stripping jaws are again placed against the cop tube in a higher position, from where the stripping process is restarted.
- the stripping jaws In order to ensure complete cleaning of the cop tube, after reaching the end of the cleaning section, the stripping jaws must be moved back into the position in which the stripping jaws were lifted from the cop tube at the beginning of the previous fault elimination process. In the subsequent supplementary wiping process, it is fundamentally possible to move the wiping jaws back to the end of the cleaning section. According to a particularly advantageous embodiment of the invention, however, it is provided that the supplementary stripping process to the area between the position of the stripper jaws at the beginning of the previous fault elimination process and the associated intermediate position is limited.
- the supplementary stripping process or processes to be carried out only takes place over the area between the position of the stripping jaws at which it was previously lifted from the cop tube and the intermediate position, i. H. at which the stripper jaws were reapplied to the cop tube in the troubleshooting process.
- This embodiment of the invention makes it possible to dispense with carrying out the supplementary stripping processes up to the end of the cleaning section. The cycle time for cleaning such cop tubes can thus be reduced, in particular in the case of several fault elimination processes.
- the cleaning section can basically be defined in any way, whereby this is usually determined by a tube monitor, which detects the surface of the cop tube to be cleaned and determines the corresponding cleaning section based on the length of the yarn package on the cop tube.
- the cleaning section usually extends over the entire winding length of the bobbin tube, and this can also be determined by a tube monitor.
- the distance over which the stripper jaws are moved to the intermediate position after the start of the process for eliminating the fault can be freely selected and can be set, for example, in a control unit. According to a particularly advantageous embodiment of the invention, however, it is provided that the adjustment path of the stripping jaws between the position at the beginning of the fault elimination process and the intermediate position is set depending on the position of the stripping jaws in the longitudinal axis direction of the cop tube and/or the number of previous fault elimination processes.
- the control unit that at an already taking place at the beginning of the stripping process Minimum speed of the stripper jaws, the displacement distance of the stripper jaws between their position at the beginning of the fault elimination process and the intermediate position is greater than is the case with a fault elimination process which is initiated when the scraper jaws - in relation to the position of use - are at a higher point on the bobbin, fall below the minimum speed. In this way it can be achieved that the number of interference elimination processes and the supplementary stripping processes resulting therefrom are reduced.
- control unit increases the displacement distance due to the number of previous interference elimination processes, in order to reduce the total number of interference elimination processes and the resulting supplementary stripping processes.
- the determination of the minimum speed of the stripper jaws which is the cause of the triggering of the fault elimination process, can basically be freely selected and adjusted in the control unit. According to a particularly advantageous embodiment of the invention, however, it is provided that the fault elimination process is only carried out when the stripper jaws come to a standstill.
- the speed of movement of the stripper jaws is detected in the manner according to the invention and a fault is eliminated only when the stripper jaws come to a standstill.
- the number of fault clearance processes and the subsequent supplementary wiping processes can be reduced in a special way after it has been ensured that the maximum possible length of the cleaning section is cleaned by the thread scraping device until a necessary fault clearance process occurs.
- the invention also solves the problem by a device for carrying out a method for cleaning a arbor on a movable carrier of a cop and Tube transport system arranged cop tube according to one or more of claims 1 to 5, with a thread stripping device with stripper jaws adjustable in the longitudinal direction of the arbor along the surface of the cop tube and a hold-down device with a hold-down element for locking the cop tube on the arbor and a control unit which controls the speed of movement of the stripper jaws and, if the speed falls below a defined minimum, carries out a fault elimination process, in which the stripping jaws are disengaged from the surface of the cop tube, then adjusted within the cleaning section in the direction of the hold-down element into an intermediate position and then placed against the surface of the cop tube again in the intermediate position , after which the wiping process is started again until the end of the cleaning section is reached and then the wiping process as supplementary wiping fprocess in the area of the position of the stripper jaws at the beginning of a previous one
- the inventive device allows cop tubes with any
- control unit ensures that the bobbins are cleaned over the entire cleaning distance to be defined.
- Fig. 1 shows a process sequence of a cop cleaning without standstill of the stripper
- FIG. 2 shows a process sequence of a bobbin cleaning with the stripping jaws stopping during the cleaning process.
- the stripping jaws of the thread stripping device are placed in a lower region of the cop tube at the start of the cleaning section, based on the position of use, with the cleaning section extending over the length of the yarn winding of the cop tube to be cleaned.
- the stripper jaws After the stripper jaws have been applied to the surface of the cop tube, they are moved in the direction of the hold-down device, by means of which the cop tube is locked on a arbor of a movable carrier of a cop and tube transport system.
- the stripping process begins, and this is carried out without the stripping jaws stopping, so that there is no fault elimination process.
- completion of the stripping process i. H. after the stripper jaws have reached the upper end of the cleaning section, they are lifted off the cop tube and moved to their starting position. The cleaned cop tube can then be transported on for further use.
- the stripping jaws come to a standstill, which is detected by a control unit. This then starts a fault elimination process, whereby the stripper jaws are first lifted off the cop tube. This is followed by a displacement of the stripper jaws into an intermediate position on the cop tube which is arranged higher--relative to the position of use--at which point they are then placed against the cop tube again. After the contact of the scraper jaws, the cleaning process is started again and the scraper jaws reach the end of the cleaning section without further standstill, whereby the cleaning process is ended.
- the stripper jaws are then lifted off the cop tube and returned to the position in which they came to a standstill at the beginning of the previous fault clearance process. In this position, the stripper jaws are then placed back against the cop tube and a Supplementary wiping process, during which the wiping jaws are moved again to the end of the cleaning section without further standstill.
