Definitions
- Spooling device with a control device for controlling the contact pressure of a spool on a drive roller
- the present invention relates to a spool device according to the preamble of claim 1.
- the winding device generally has a spool arm for holding and guiding the spool.
- a rotating roller by means of which the spool is rotated by means of friction.
- the spool arm compensates the increasing spool diameter by means of a pivoting movement in such a way that the spool rests approximately at the same point on the roller driving it during the entire construction.
- REPLACEMENT LEAF a roller which drives it is controlled by means of an adjustable spring, the pressure of the coil on the drive roller caused by gravity being initially increased by means of a drive spring when the coil is being built up and then reduced later.
- the coil arm is provided with a lever which, as part of a rocker arm joint arrangement, carries the coil at one end, while a spring acts on it at its other end.
- the rocker arm joint passes through its extended position, the spring not generating any force pressing the coil.
- the extended position of the rocker arm joint is left again, so that the spring now exerts a force lifting the spool on the spool arm.
- the spring force falling due to the expansion of the spring is more than compensated for by a longer lever arm which the spring engages.
- the purpose of this device is to keep the contact pressure of the coil on the drive roller approximately constant during the entire construction of the coil. With a suitable choice of the corresponding rocker arm lengths of the rocker arm joint, it is also possible to reduce the contact pressure of the coil on the drive roller as the spool diameter increases. Depending on the intended use of the finished spool, it is desired that it be wound with different contact pressure, for example with dye spools
- the spring of the winding device of DE-OS 22 17 295 has an adjusting screw, with the help of which the bias of the spring can be changed.
- DE 25 18 646 C2 a device for controlling the contact pressure of a textile bobbin is known, in which the stretched position of the rocker arm joint arrangement and, at the same time, the pretension of the loading spring can be changed.
- REPLACEMENT LEAF Pressure control device contains a predetermined contact pressure correction curve, with which a drive device for the bobbin holder is controlled via the current bobbin diameter. For this purpose, the ratio of the speed of the spool and the drive roller for calculating the take-up spool diameter is recorded and the drive device for the spool arm is controlled on the basis of the predefined assignments of diameter and contact pressure.
- a winding device of a winding machine in which the device for pressing the bobbin against the drive roller has two compression springs, with the help of which ultimately a resultant force is exerted on the rocker arm arrangement, in which the spool is first pressed onto the drive roller, and when the spool diameter increases, it is lifted counter to gravity.
- the aim is to exponentially reduce the contact pressure between the spool and the drive roller as the spool increases.
- the requirements for a winding device in the future will be that the winding condition, for example the contact pressure of the bobbin depending on the current operating situation, for example when piecing, after thread breakage, when threading on the sleeve or the formation of a thread reserve, can be adjusted quickly and automatically.
- the winding condition for example the contact pressure of the bobbin depending on the current operating situation, for example when piecing, after thread breakage, when threading on the sleeve or the formation of a thread reserve.
- the device of DE 25 18 646 C2 e.g. has the disadvantage that the setting shown here
- REPLACEMENT LEAF Device only a few spinning positions are adjustable at the same time. In the spinning / winding machines customary today, which can have about 280 spinning positions, this device can only be used with great effort. In addition, it has the disadvantage that, due to mechanical play, the adjusting device can generate different forces at different winding positions, as a result of which the bobbins are wound differently from spinning position to spinning position. In addition, the setting of the contact pressure is time-consuming and requires trained personnel. A change in the setting during operation is practically not possible, the change cannot be automated.
- the control device of DE 39 11 854 AI requires great effort to record the various speeds and a complex and complex device for controlling the contact pressure device.
- the devices shown in the rest of the state of the art partially fulfill their purpose for their special use, but are completely inflexible, so that they require a great deal of effort if, for example, another fiber material or a different bobbin density is to be wound or the machine shows that the contact pressure has to be increased or decreased.
- the object of the present invention is to improve the state of the art in order to create a simple, inexpensive, space-saving and flexible winding device which avoids the disadvantages of the prior art and in which the setting of the contact pressure for a bobbin can also be automated , and the contact pressure for individual winding units or winding unit groups can be set differently.
- the object is achieved by the features of claim 1.
- a loading means which first presses the bobbin onto the drive roller and later lifts off the bobbin with increasing bobbin mass to avoid excessive contact pressure
- a simple, inexpensive and space-saving means enables a favorable basic loading of the bobbin becomes.
- the additional arrangement of a pressure cylinder allows the predetermined contact pressure of the spool to be changed in a simple manner, so that a flexibly usable spool holder is created which can change the contact pressure given by the pressing means in a simple manner and over a wide range.
- REPLACEMENT LEAF the entire coil structure does not reverse its rotating action on the coil holder, it is achieved that the level of the contact pressure is changed in a uniform direction during the entire coil structure. This means that it is either increased or decreased during the entire coil build-up.
- the use of a pressure cylinder ensures that this change in the contact pressure is made possible with simple means at all winding positions of a spinning or spinning machine. Due to the possibility to apply the same medium pressure to all bobbin holders of a machine, the bobbins are wound with the same contact pressure at all bobbin positions. The medium pressure can easily be kept constant. Any number of winding positions on a machine can thus be operated with the same contact pressure of the spool on the drive roller.
- the moment exerted by the pressure cylinder increases the pressing force of the coil.
- the loading means it possible for the loading means to be designed with only the minimum force which corresponds to the lowest contact pressure, so that it can be made very inexpensive and small and the additional contact force required can be adjusted by simple means using the pressure cylinder.
- the driving force of the coil is reduced by the pressure cylinder.
- REPLACEMENTB rigt As a result, energy-saving, low air pressures can be used if, for example, work is essentially carried out on the winding units of a machine with high contact pressure.
- the bobbin holder becomes particularly flexible if the pressure cylinder has a piston which can be acted upon from both sides, which means that the base load on the bobbin holder can be both increased and decreased. It is particularly favorable if the pressure cylinder is connected to a supply line which is already acting on it with a predetermined pressure. This makes it possible to use a single pressure control device to constantly set and maintain the pressure at all winding positions.
- the supply line has the great advantage that it can be designed flexibly, so that no special precautions need to be taken when designing the overall machine.
- the pressure cylinder is connected to a second supply line via a valve, as a result of which it is possible to apply a different medium pressure to individual winding units or groups of winding units during operation of the spinning or winding machine than the other winding units . This is particularly the case
- REPLACEMENT LEAF Partially if different types of yarn with different lay-up pressures are to be wound on one machine.
- the two supply lines are operated with predetermined different pressures.
- This can be used, for example, when attaching a thread to a sleeve or when accelerating a bobbin after a thread break.
- the operator or the automatic control device can control the connection of the piston to a specific supply line. This saves, for example, special pressing means that were previously housed in the operator control.
- the desired pressure is available at all times. It is particularly advantageous that the pressure is kept centrally constant at the desired level via a pressure control device. By adjusting the pressure of each individual supply line, the exact pressure required can be generated, and this can also be changed while the machine is in operation. The pressure can also be set automatically if the spinning / winding
- REPLACEMENT LEAF a device is provided, with the aid of which the machine controls, for example, the appropriate draft from the desired yarn parameters entered.
- This device can also be used to automatically set the associated contact pressure of the spool.
- the pressure cylinder is assigned a controllable valve with which the pressure cylinder can be separated from the supply line or to which one or the other supply line can be connected. It is particularly advantageous if the pressure cylinder can be decoupled from the supply line, if no force changing the contact pressure of the coil is desired continuously or temporarily. It is advantageous if a valve assigned to the pressure cylinder can be operated by the control device of the spinning / winding machine. This ensures that the device can be automated.
- valve which alternately connects either the front or rear side of the piston to a supply line.
- this valve is automatically controlled by the machine. If necessary, it is advantageous if the action on the piston can be changed individually at the winding point, for example when piecing or after
- FIG. 1 shows a winding device 1 in the side view
- Figure 2 shows a winding device with a control device in which the piston of the cylinder can be acted on on both sides;
- FIG 3 shows the front view of the Spuleinrich ⁇ device of Figure 1, partly in section.
- the control device 2 from FIG. 1 consists of a loading means 20 and a cylinder 21, both of which attach to the coil holder 3.
- the coil holder 3 can be pivoted about an axis 30 in order to compensate for its increasing diameter by a pivoting movement when the coil is being constructed.
- the loading means 20 and the cylinder 21 act on the coil holder 3 via a lever 31 and are supported on a receptacle fixed to the machine frame.
- the loading means 20 is essentially a spring 200, which is guided in a two-part guide 201 to prevent buckling.
- the spring 200 has a pretension so that it exerts a moment on the bobbin holder 3 via the lever 31 in such a way that it is pressed in the direction of the drive roller. This means that the spool 4 is pressed onto the drive roller 40 in addition to its own weight.
- the bobbin holder 3 is pivoted about its axis 30, so that the lever 31 / loading means 20-joint arrangement is brought into an extended position so that no more moment is exerted on the bobbin holder 3. In this position, the pressing force of the coil 4 on the drive roller 40 is caused solely by the weight of the coil and the bobbin holder.
- the loading means 20 exerts a moment on the coil holder 3,
- the loading means 20 is combined with a cylinder 21 in accordance with the invention in such a way that the cylinder 21 exerts a force on the lever 31 which presses it towards its drive roller during the entire construction of the coil. This is achieved through suitable leverage ratios.
- a cylinder In contrast to the loading means 20, when the cylinder 21 is acted upon by a pressure medium, a torque with a constant direction of rotation is exerted during the entire coil construction.
- a cylinder is shown with a piston 212, which can be pressurized only on one side via the cylinder space 210.
- the cylinder space 210 is connected via the connection 211 to a supply line 5, not shown in FIG.
- the pressure in the cylinder space 210 causes the piston 212 to exert a force on the lever 31 via its piston rod 213, which causes the coil 4 in Direction on their drive roller 40 is pressed. In the present exemplary embodiment, therefore, by acting on the cylinder 2, the contact pressure of the coil 4 is increased further.
- the increase thus takes place from a basic setting of the contact pressure which is generated by the loading means 20.
- the loading means 20 allows the contact pressure for the spool to be preset by means of a simple, inexpensive and space-saving element which, however, is very inflexible in its own right and is arranged differently in the receptacle for an adjustment of the contact, the contact pressure that would have to be changed or, for example, the pretension of a spring 200.
- REPLACEMENT LEAF are applied, which can be kept constant during the entire coil build-up.
- a pressure control device which is controlled as a function of the spool structure is eliminated.
- the control device 2 of FIG. 2 has a cylinder 21, the piston 212 of which can be acted upon by pressure medium on both sides.
- the cylinder 21 has two connections 211 for the supply of the pressure medium.
- the cylinder 21 can be used either to increase the contact pressure of the coil 4 during the entire coil build-up or to reduce the contact pressure of the coil 4 during the entire coil build-up by reversely acting on the piston 212.
- 5 pressure medium is made available via supply lines.
- Two supply lines 5 are assigned to spool device 1 of FIG. These carry pressure medium with different pressure levels.
- the cylinder 21 can optionally be connected to one or the other supply line 5 via an electromagnetic valve 50.
- a second solenoid valve 51 can be used to control which side of the piston 212 of the cylinder 21 is to be pressurized. Each valve is connected to the control unit (not shown) of the valve via electrical control lines 6.
- the control unit of the machine can then connect each individual winding point to the pressure of one or the other supply line 5 via the solenoid valve 50.
- the control unit of the machine controls via the solenoid valve 51, whereby it is also possible for each winding unit of the machine to determine whether the contact pressure should be increased, decreased or not influenced.
- the two solenoid valves 50 and 51 can also be connected via control lines 7 to an operating and maintenance carriage 11.
- each individual spinning station can be controlled from the maintenance carriage via the corresponding application of pressure to the piston so that, for example, there is a high bobbin load if the bobbin accelerates quickly when the thread is reattached must be.
- valve 50 is switched so that it connects the piston 212 to the supply line 5, which carries the higher pressure, and the valve 51 so that the piston 212 is pressurized via the cylinder space 210.
- the valves 50 and 51 are returned to their starting position.
- the valves 50 and 51 are controlled by the control unit of the machine alone. To do this, it is then necessary for the operating carriage 11 to communicate with the control unit.
- FIG. 3 shows the front view of the winding device from FIG. 1, the arms of the bobbin holder 3 carrying the bobbin being shown in section. From Figure 3 it is clear that the control device 2 with the loading means 20 and the cylinder 21 need not be arranged in one plane. In FIG. 3, the loading means 20 attacks more near the left arm of the bobbin holder 3, while the cylinder 21 engages more near the other arm of the bobbin holder.
- the cylinder 21 has a solenoid valve 51 arranged on its cylinder wall, which is connected to the connections 211 by short lines. Solenoid valve 51 is connected to supply line 5, not shown, via line 53.
