Definitions
- the invention relates to a creel, in particular for slip machines, with the winding units assigned Thread guiding devices, each a thread clamp that can be switched when the machine is at a standstill have, the thread inlet side of the thread in opposite directions wrapped brakes are assigned, and with a thread outlet on the thread clamp distant, designed as a thread monitor needle Thread deflection point.
- Coil creels are provided with coils at their winding positions equipped, the threads of a winding machine subtracted from. They usually have to be braked to the orderly Winding to generate required thread tension. However, the thread speeds can be so become large that a braking of the threads when pulling from the coils is no longer required.
- the through a thread deflection from the creel to the winding machine achieved thread resistance as a result of Game friction at the deflection point and resistance to air friction of the thread can become so large that additional braking is not necessary. But it will a thread clamp is required to hold the thread at standstill the winding machine is stuck. All thread clamps of the gate keep the coulter for the standstill of Winding machine and arranged for its restart.
- the invention has for its object a creel with the characteristics mentioned above improve the risk of contamination buildup significantly reduced in the thread clamps becomes.
- the contaminants transported by the thread can be deposited directly on the thread clamp. They are stripped off when the thread is in the thread clamp runs in or runs out of the thread clamp. During this run-in, the thread brushes against guide elements the thread clamp or on this even along and pollutes the latter.
- the basic path is now taken, a wiping of dirt on the thread clamp by avoiding the thread in the open Thread clamp is guided without contact.
- the Thread guide device designed accordingly. It ensures that the thread is not on one Jaw can slide along the thread clamp, still on an abutment of this thread clamp. Deposits of contaminants are avoided.
- the pre-brake rod or the thread of the thread clamp feeding component are in a predetermined Distance from the thread clamp and can be designed there so that there is abrasion a comparatively large deflection radius does not arise or due to the distance from the thread clamp does not get into their functional area.
- the creel is designed so that three pre-brake rods are available, of which also the next coil is fixed, while the middle loop is adjustable.
- the pre-brake rod closest to the clamp ensures that the entry position of the thread is constant remains.
- the closest pre-brake rod acts essentially comparative to that of the coil tapering thread, which as a result of rapid thread take-off forms a so-called thread balloon and the middle pre-brake rod is arranged so that the desired wrap or thread braking is achieved. With the help of their adjustability can meet the operational requirements of the creel are sufficient.
- Pre-brake rod is hollow and at least one on the thread clamp has directed air nozzle. With the help of the air nozzle can the thread clamp can be cleaned if there is any contamination collect from the area surrounding the terminal.
- the pre-brake rod used for this provides not just a contribution to influencing the thread tension and for the contactless guidance of the Thread in the area of the open thread clamp, but it also serves to supply compressed air Air nozzle, which in the simplest case has a hole in the hollow Pre-brake rod can be.
- the thread clamp usually has a cross to Direction of thread considerable horizontal and vertical Expansion. It can therefore be advantageous to use the creel to train so that at least two are vertical stacked air nozzles at a winding unit are present, the thread clamp and their Generate a cleansing air curtain.
- the Air curtain is conveniently placed on those Area of thread clamps directed from the thread is going through. The remaining areas of the air curtain also clean and contribute to an orderly Blowing away the impurities.
- the air curtain swivels and / or transverse to the direction of the thread in the area of the winding unit Is translationally movable can be much larger areas blow the thread clamp and its surroundings than through a fixed air curtain.
- the cleaning effect can be influenced accordingly become.
- the air curtain swivels becomes the greatest cleaning effect in the thread pass area reached the thread clamp while with translatory adjustment of the air curtain all Areas of the thread guide device as a result of this constant distance cleaned in the same way become.
- the pre-brake rods already mentioned it should be included in the cleaning expedient to form the creel so that three Pre-brake rods are present, of which the two outer opposite to the middle during a Spool changes are adjustable.
- the thread clamps next to the pre-brake rod which at your Training as a hollow bar and provided with an air nozzle is for cleaning the thread clamp and its Environment, taking it close to the coil Brake rod can form a structural unit, whereas the middle pre-brake rod from one Module is independently adjustable.
- the creel can be designed that the air jets at the winding positions of a single one Gate field or at all winding points of the gate can be pressurized with compressed air at the same time. Compressed air cleaning all winding positions of the gate at the same time requires a suitably powerful compressed air system. Such an interpretation is not necessary when the winding units of a single gate field are cleaned that are equal to the number of fields Many times less are numerous. Optimal cleaning will be done in this case when the air vents different gate fields can be cyclically loaded are. It can then be cleaned continuously with each gate field due to cyclic swapping cleaning again as soon as possible becomes. This cyclic, for example, gate-field-wise Cleaning is particularly beneficial, though the suction from the area of the thread clamps blown away contaminants is carried out cyclically. Such a distance from Example by suction pipes is then less expensive in terms of equipment.
- the creel can also be designed in this way that the middle pre-brake rods of the winding units of a creel, the greater the wrap the closer they are to the note machine are located.
- the pre-brake rods for the contactless guidance of the thread clamp of the thread it is possible on the different free thread length of a creel consideration to take and the brake rods in the sense of a Use thread tension compensation.
- the coil gate 10 shown in FIGS. 1, 2 is a so-called V-gate, of its two V-legs 10 'threads F of a winding machine, namely a slip machine 11, from which the threads F a winding tree 21 are wound up between whose winding disks 11 'have a pressure roller 22 which are constantly increasing in diameter during winding Presses.
- the winding process is carried out by one Control panel 23 of the winding machine controlled by where the winding machine is also switched off can, if there is a break in a thread F.
- the creel 10 has a larger number of Gate fields 20 in which the coils 24 in conventional Are arranged in rows and columns.
- Fig.2 shows schematically reversing gate 25, the interior 26 of the creel 10 can be fitted out can while on the outside of the V-leg 10 'the threads are removed.
- the winding unit 12 of the gate 10 is in FIGS schematically shown enlarged. From the coils 24 if the thread F is taken off overhead, one passes through Thread guide device 13 and is in the direction of Winder 11 deflected. So that all threads F the Thread group in the event of the winding machine coming to a standstill 11 ordered in the same way to a standstill come, each thread guide device 13 has one Thread clamp 14, which is attached to a gate strut 26 is.
- the gate strut 26 is part of the other gate frame, not shown, from which the coils 24 are also carried.
- the gate strut 26 is open on the side, so that at least in the hollow interior 28 partially a tubular housing 27 of the Thread clamp 14 can be installed permanently.
- This Housing has an external abutment 29, with the one perpendicular to it adjustable in the display plane Clamping jaw 30 cooperates.
- the jaw 30 is perpendicular to one in the plane of illustration adjustable to the gate strut 26 or to the housing 27
- Bolt 31 held in the housing 27 such is that the jaw 30 is only corresponding this leadership can move.
- Thread clamp 14 is the jaw 30 so far from Abutment 29 removes that the thread F without the touch the thread clamp 14 between the jaw 30 and the abutment 29 can pass through.
- the thread also has no contact with the bolt 31, as shown in Figure 3, because it is located above this bolt is.
- the thread clamp 14 is operated such that the Ramp 33 moved in the direction of arrow 34 becomes. Then the clamping spring 32 can follow the bolt 31 press right and the jaw 30 clamps the thread F together with the abutment 29.
- control spring 35 is here not received because their function is detailed in European Patent 0 311 781 as described in the rest also the further configuration of the here so far Thread clamp 14 described description and drawings given there with full reference taken, also with regard to the control of the thread clamp especially when the winding machine starts up after standstill.
- the thread guide device 13 also has another holder 36 for a thread monitor needle 17, which with a pivot bearing 37 on the housing 27 of the Thread guide device 13 is attached. From the Fig. 3.4 it can be seen that the thread monitor needle 17 Deflection of the thread coming from the bobbin 24 F is used for winding machine 11.
- the needle 17 is arranged that they share with a pre-brake rod 15k the thread between the jaw 30 and the abutment 29 holds such that it is contactless between the two aforementioned components 29.30 runs.
- the thread is between the two Components 29,30 the distance x available and the guard needle 17, as well as the pre-brake rod 15k, keep the thread F on x / 2.
- the Brake rod 15s with respect to the axis 39 of the coil 24 or aligned with respect to the thread clamp 14 is like the pre-brake rod 15k. All pre-brake rods 15 are arranged parallel and vertically to each other. As a result, they run parallel to the gate strut 26. To the thread course described above to achieve the thread F are both pre-brake rods 15k, 15s cannot be adjusted during winding operation.
- a third pre-brake rod 15m is provided, which is arranged so that the thread F one more or less large loop 38 forms.
- a reduction in the size of the loop 38 can thereby be achieved be that the middle brake rod 15m in the dash-dotted position 15m 'is adjusted. It is hardly there is still a wrap around the pre-brake rods 15, however, which is sufficient to counter the thread F to press the pre-brake rod 15k so that the non-contact Thread course in the area of the thread clamp 14 remains guaranteed.
- the pre-brake rods 15 are in the creel 10 with different settings of their pre-brake rod 15m used.
- the position shown in Fig.4 is used in the area of those coils 24 that the Wrapping machine 11 are closest, so in which the free running thread length is shortest and therefore the influence of the ambient air on the thread Air friction is lowest.
- the loop 38 provides a corresponding action on the thread F, the is therefore just as strong as a thread F that runs from an end region 10 "of the creel 10. In this area 10 "there is an additional application of friction the thread F is not necessary, so that the pre-brake rod the position shown in Figure 4 Takes 15m '.
- Fig.4 shows; that the pre-brake rod 15k is hollow and has an air nozzle 18, namely a hole. With pressurized air of the cavity 39 of the pre-brake rod 15k compressed air flows out through the air nozzle 18, which is directed to the thread clamp 14, in particular to the area between the jaw 30 and the abutment 29. If several air nozzles 18 arranged one above the other, results in vertical to 4 an air curtain 19, the one Brush greater height of thread clamp 14 can, which may be necessary because, for example the jaw 30 and its abutment 29 over extend a larger vertical area.
- a Pre-brake rod 15k is a plurality of air nozzles 18 one above the other available for several winding units.
- the cavities 29 several parallel to each other Pre-brake rods 15k of different gate field columns can be pressurized together. This will allow many thread clamps to be cleaned at the same time 14 reached, not just as far as it was one Pre-brake rod 15k are assigned. It will for example the thread clamps 14 of an entire Gate field 20 or even all gate fields 20 cleaned.
- the vertical pre-brake rods 15k can be horizontal are moved, i.e. transversely to their longitudinal extent, around the thread clamps 14 over their entire Blow width. This is conveniently done during a bobbin change, because then the contactless thread guide of thread F between the jaw 30 and the abutment 29 is not given. While of the coil change are the pre-brake rods 15k, 15s on the one hand and 15m on the other hand so far apart driven that an effortless pulling of the thread F from the coil 24 into the clamping device 13 is possible. Then the pre-brake rods 15 moved back into the positions shown in FIGS. so that their wrap through the thread is achieved.
