Definitions
- the present invention relates to a power supply for the winding units of a winding machine, which is a winding unit with a spindle drive, a sensor for speed and / or position of the spindle and a thread traversing device with a drive, the spindle drive and the thread traversing device being electronically connected to one another are synchronized.
- the winding unit also contains the so-called thread run, these are the components from the attachment for the bobbin to be rewound to the thread traversing device, for example a thread monitor and a thread brake or insulation.
- a plurality of up to 60 or more winding units or spindles is arranged in a common frame and forms a winding machine with a common control cabinet, which among other things contains the power supply for all winding units.
- An example of such a winding machine is the precision cross winder PW1 preciflex from Shurer Schweiter Mettler AG.
- Suitable winding units are described, for example, in EP-A-0 453 622 and EP-A-0 829 444 and EP-A-0 838 422. If there is any during the operation of such If the winding unit comes to a power failure, the thread traversing device is at a standstill after a very short time silent, whereas the coil because of its usually relatively large The mass continues to rotate, during which time the thread is wound onto the bobbin in parallel becomes. When restarting, the wound position of these parallel turns must be can be peeled and cut by hand, which can be considerable Material loss means. In addition, this requires at each winding unit manual intervention takes a considerable amount of time, so that a Power failure negatively affects productivity.
- the invention is now to improve the known winding machines so that Power failures no longer with such serious and manual intervention by the operating personnel necessary consequences are connected. But that comes in itself obvious solution, namely equipping the winding machines with a conventional one Emergency generator that feeds the entire winder, for cost reasons alone out of the question. Apart from that, such an emergency generator would be because of the high Number of spindles too big and too heavy.
- the achievement of the object according to the invention is characterized in that a power storage device that can be activated automatically in the event of a power failure is provided, which on the one hand the sensor mentioned and on the other hand the drive of the thread traversing device powered so that the synchronism between the spindle drive and the thread traversing device is maintained.
- the arrangement according to the invention therefore maintains the synchronism between the spindle drive and thread traversing device until the bobbin comes to a standstill so that Controlled thread laying also takes place while the bobbin is running out. If the power failure is short, where short here means that the power failure before standstill the coil is finished again, then it is bridged by the arrangement, if it is longer, then an orderly stopping of the winding unit and thus the winding machine is made possible.
- a second preferred embodiment of the power supply according to the invention is characterized in that the power storage device by a static uninterrupted Power supply is formed.
- UPS uninterruptable power supply
- this drawing is a block diagram of the control of a The winding unit and the power supply of the winding machine shows.
- reference numeral 1 designates the power supply of a winding machine and reference numeral 2 designates a winding unit control, the winding machine consisting of up to 60 or more winding units with winding units. Since the winding unit itself does not form part of the subject of the present invention, a detailed description is omitted here and in this connection EP-A-0 453 622, EP-A-0 829 444, EP-A-0 838 422 and to the preciflex precision cheese winder marketed by Shurer Schweiter Mettler AG.
- the winding units contain certain components that belong to the basic design, as well certain optional components, the components of the Basic version in a block 2.1 and the optional components in a block 2.2 are summarized.
- the basic version contains in particular a spindle drive 3, a sensor 4 assigned to the spindle drive for rotational speed and / or rotational position the spindle and thus the bobbin, a thread traversing device 5, a sensor 6 for the bobbin diameter to stop the diameter of the spindle drive 3, a thread monitor 7 and a preferably magnetically actuated thread insulation 8.
- Dem Spindle drive 3 is a detector 9 for monitoring the power supply Operable switch 10 upstream to interrupt the power supply.
- the optional components summarized in block 2.2 include, for example a delivery plant 11, an insulation 12 assigned to the delivery plant and the oiling 13 of the Winding unit.
- a delivery plant 11 for example a delivery plant 11
- an insulation 12 assigned to the delivery plant
- the oiling 13 of the Winding unit the illustration is only to be understood as an example; in particular Both the block 2.1 and the block 2.2 can still other components exhibit.
- the power supply 1 contains a network transformer 14, after the output of which Dividing supply into two paths P1 and P2 to block 2.1 and 2.2 respectively.
- Path P2 contains one AC / DC converter 15 and a switch 16 and the path P1 contains a switch 16 ', both in the closed state connecting to the supply produce and interrupt them in the open state.
- the path also points P1 in front of the switch 16 'one for the input of a static uninterruptible power supply (UPS) 17 leading turn.
- UPS 17 which two with the paths P1 and P2 has connected outputs, controls the two switches 16 and 16 'and is also used for the detection of network failures and drops in network voltage a certain value. All electronics of the UPS 17 for control and monitoring as well as all switching elements are in the central power supply of the Integrated winding machine, which is preferably located in a control cabinet. The The required battery pack is placed next to or on top of the control cabinet put on.
- the described device functions as follows:
- the UPS 17 monitors the supply and switches when a power failure or a drop is detected Supply voltage below a certain level by opening switches 16 and 16 ' Emergency power supply around.
- the detector 9 of the spindle control 2 also monitors the Power supply and opens the switch when the supply voltage falls below a certain level 10 and thereby switches off the main power consumer, namely the spindle drive 3. This continues to rotate with its swing energy.
- the detector 4, the thread traversing device 5 and all elements of the thread run are further powered by the UPS 17 provided.
- the UPS 17 By feeding the detector 4 and the drive of the thread traversing device 5 the UPS 17 ensures that the spindle drive 3 can run out undisturbed and that the synchronism between the spindle drive and the thread traversing device 5 is retained, so that the thread laying until the spindle drive comes to a standstill based on the set parameters and only the desired one on the spool Winding is produced.
- the feeding of all elements of the thread path enables the Maintaining the desired thread delivery and thread take-off conditions. For the If the bobbin produced with the winding unit has such a low mass, that their kinetic energy is not sufficient to allow the coil drive to run out undisturbed let the kinetic energy of the coil and coil drive by an additional mass enlarged.
- the control of the UPS 17 is designed so that one short "drop in line voltage or a short "mains failure, which ended before the spindle drive 3 came to a standstill, the winding units of the winding machine are switched back to the mains Short "power failure is defined on the basis of a corresponding time interval of, for example, 3 seconds, but this time interval is significantly shorter than the time until the spindle drive comes to a standstill.
- the UPS 17 deactivates again, closes the switches 16 and 16 'and thereby switches over to normal supply.
- the spindle drives 3 are switched on again (the switches 10 are closed) and accelerated to their target speed, so that the winding machine continues to work without significant loss of time.
- Such a Short "power failure only leads to the winding machine running slower for a short time of a few seconds.
- the spindle drive 3 not switched on again. It is let out with its swing energy and the UPS 17 feeds for an adjustable period of time, for example between 30 and 90 seconds all secondary power consumers, so an orderly shutdown to ensure. After this period, the UPS 17 is deactivated and the winder waiting for the power supply to return. As soon as this exists, behaves the winding machine turns on as with the main switch, i.e. the control the UPS 17 and the winding unit controls 2 initialize and the thread guide moves to the two end points of its traversing interval, for example.
