Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding beam for textile materials having a damping device consisting of a damping device, a transmission device and an actuating device.

In high-speed warping machines, broken threads or 2
The problem is to stop the winding beam in any winding state before the thread being pulled off the pin has not yet been wound onto the winding beam and therefore the thread is not easily found.

The object of the invention is to adjust the braking force at any time depending on the operating conditions, so that the winding beam can be stopped instantly from any winding state and at any winding speed. As a result, the requirement is met that the predefined winding length of the fiber material is not exceeded from the start of the braking process until the stop of the winding beam.

In order to solve this problem, according to the present invention, a braking device has a diagonal force adjusting device, the braking force adjusting device has a plurality of adjusting parts i, and each of the adjusting members has a diagonal force adjusting device. The at least one parameter influencing the power is each itself adjustable. Preferably, the adjustment elements are combined into a summing device. For example, a predetermined number of adjusting elements are used for parameters that are constant for the winding stroke in question, and at least one adjusting element is used for parameters whose value changes during the winding stroke.

At least one adjustment member each has a constant parameter, (a) the friction value of the braking device and/or the total removal device, (b) the winding body milling (or) the specific gravity of the yarn, and (c) the winding body. and (or) the length of the winding beam, and the parameters provided for the braking time and at least each of which is varied by at least one adjusting member, namely (e) the winding speed, (f) the diameter of the winding body. Advantageously, it is provided for

, the parameters described in (e) and (f) above are related to each other. The circumferential speed of the winding is incorporated into a constant parameter during the braking time mentioned in the second item, which is related to the respective diameter of the winding and the rotational speed of the winding beam.

However, it is also conceivable that a varying braking time is desired, for example as a function of the circumferential speed of the winding. The winding speed described in (e), that is, the circumferential speed of the winding body, is incorporated into the changing parameters. However, it is also possible that the winding speed is constant. As is clear from this, it is not always possible to accurately distinguish between constant parameters and changing parameters.

However, it is important that all parameters controlling the braking force are detected as accurately as possible and fixedly adjusted in advance accordingly. Or, during the winding process, it is always at the point of post-adjustment.

The braking device itself can have completely different embodiments. Typically, mechanical friction brakes, hydraulic brakes or pneumatic brakes are used, such as ram brakes, jaw brakes, disk brakes, band brakes. However, even if not conventionally used, electric eddy current brakes, electro-hydraulic brakes, hysteresis brakes or others can also be considered. Therefore, different media are required to apply the braking force.

According to a further embodiment of the invention, the brake force adjustment device has an active connection to the transmission device in the brake device or to the actuating device. That is, it is possible to act on the transmission device, for example in such a way that the lever length of the transmission lever can be changed.

However, it is also possible to directly influence the actuating device, for example so that the pressure acting within the piston-cylinder mechanism changes.

In a further embodiment of the invention, the operative coupling comprises a serve motor and/or a mechanical lever device and/or an electrical, pneumatic or hydraulic transmission device and/or a fluid pressure adjustment. It has a container. Advantageously, the actuating device has a pneumatic piston-cylinder arrangement, which has an active connection to a fluid pressure regulator, in which case the braking force regulation is A working connection starting from the device is guided to a fluid pressure regulator.

Furthermore, the fluid pressure regulator may already be part f of the braking force regulator. In this case, the working connection between the hydraulic pressure regulator and the pneumatic piston-cylinder mechanism is always an oscillating working connection "t!l".Alternatively, the hydraulic piston-cylinder arrangement A cylinder mechanism may also be chosen, in which case the fluid used is suitably pressurized oil rather than, for example, pressurized air.However, in the case of winding machines for textile materials, pneumatic The braking system has proven to be better.

In a further embodiment of the invention, the braking force adjustment device has an electrical circuit arrangement, which circuit arrangement is connected to the thermomotor, and in which the braking force adjustment device has an electrical circuit arrangement that is connected to the thermomotor.
! is adjustable as an electrical value. In this case, electrical or electronic circuit arrangements of the usual type are conceivable.

In the case of a serze motor, there is no special serse motor at all, but a general type serse motor can be considered. , in this case, what is important is that the parameters can be adjusted as electrical values.

For this purpose, it is advantageous if the electrical circuit arrangement has potentiometers for adjusting parameters, even if only the corresponding electrical values are important for the circuit arrangement itself. Preferably, every individual potentiometer has a graduation indicating the natural value of the parameter. The potentiometer can be connected, for example, to an adder, the output lead of which is coupled to the serze motor. In other words, the addition of the solometers is carried out in one electrical path in this case.

However, as an alternative to this, the braking force adjustment device can also have a mechanical addition transmission.

Such a summing gear can be used, for example, as an i-wheel gear or as a speed increasing gear. and its overall length forms a measure for the braking force to be adjusted. In most cases there can be a rod ``'r!'' of variable length, which rod acts on a fluid pressure regulator, for example consisting of a pressure reducer.

The length-adjustable adjusting member consists, for example, of a nut and a screw, which are rotatable relative to each other. That is, the screw can be fixed and the nut rotated, or the nut can be locked and the tilt can be rotated.

However, it is also conceivable to simultaneously rotate the image parts with respect to each other and thereby effect the meter adjustment. In the preferred embodiment defined, the bolt has a central bore and is slidably and rotatably mounted on the rod. The rod is used in this case only as a guide. Furthermore, the nut has an anti-rotation device and advantageously has a drive wheel, which can be used as a notched wheel for manual adjustment or for mechanical or remote adjustment. It can be configured as a chain wheel for use. In this case, the length-adjustable adjusting members are preferably supported on one another by axle bearings, linear bearings or grooved rolling bearings. Such axial bearings, for example rolling bearings, can in particular be constructed as ball bearings. Length-adjustable adjusting members arranged side by side and axially supported to each other by bearings and each slidably supported on a rod by means of a bolt section are generally adjustable in length as a whole. forming a sleeve. In this case, it is advantageous if the last adjusting member of the summing gear constructed in this way has a bushing that is slidably and rotatably arranged on the rod, which bushing is connected to the drive gear and the cam track. and an edge region with a trace roller supported on the edge region, which trace roller itself is connected to a bushing which is slidably but non-rotatably mounted on the rod. and the bushing is connected to the fluid pressure regulator, to the actuating device,
or has an operative connection to a transmission device. The cam trajectory is empirically defined or calculated. The cam trajectory must be taken into account in such a way that, in conjunction with the defined braking time, the braking moment first decreases as the winding diameter increases, but then increases again.

This results from the configuration of conventional winding beams and winding machines.

Of particular note is the parameter ′ that changes during the winding process.
t% ah. According to a further embodiment of the invention, therefore, a rotational speed detector and a winding speed detector are provided, in which case an operative connection from each detector to the adjusting member is provided. For example, a tacho generator is used as the rotation speed detector. A tacho generator is also useful as a winding speed detector, and the tacho generator is connected to the measuring roller.
via which the yarn group runs onto the winding beam before winding. The circumferential speed of the measuring roller is in this case equal to the circumferential speed of the winding beam. In this case, the winding speed is proportional to the rotational speed of the measuring roller.

The winding speed is, as is known, related to the winding beam rotation speed, and in this case the following relationship: For example, the measured winding speed can always be related to the reel diameter. Therefore, it is recommended that a calculator be used. Specifically, in another embodiment of the invention, a rotation speed detector and a winding speed detector are connected to a computer,
Furthermore, one output line of the computer is connected to an adjustment element for the braking time, and a second output line of the calculator is connected to an adjustment element for the winding speed and/or the winding diameter. In this case, the computer also detects the braking time, which is also dependent on the respective winding speed.
In this case, the following relationship exists:
In this case, the braking distance increases, which corresponds to the length of the material that runs onto the winding beam during the braking period.

Advantageously, in another embodiment of the invention, °
The total braking force adjustment device is designed as an electrical calculator, to which an output voltage proportional to the braking moment is applied. This output voltage optionally controls the motor of the fluid pressure regulator via an amplifier. (As long as the rollers partially wrapped around the winding beam are connected in advance (which is usual), the fiber material is not damaged at all and this In order to ensure that the thread tension is maintained, it is advantageous if the rollers are also braked.

Accordingly, in a further embodiment of the invention, the roller, for example a transport roller or a measuring roller, can be provided with a braking device, the braking device having a braking force adjustment device with at least two adjusting elements. ing. In the adjustment member, at least one ceramic element that influences the braking force is adjustable.

In order to avoid having to make special adjustments in each of the two braking force regulators, it is furthermore possible to adjust the winding beam and rollers for the winding speed and/or braking time by means of a synchronizer. It would be nice if you had .

An advantage provided by the invention is that parts can be replaced particularly quickly and accurately. In this case, if only one parameter, for example the length of the winding beam, changes, only the adjustment element belonging to this parameter is adjusted, all other adjustments remaining constant.

The invention will be explained in detail with reference to the embodiment shown in FIG.

FIG. 1 shows a warping machine 11 with a winding beam 12, which already has a winding 13 of fiber material, which in the form of threads 14 is attached to the measuring roller 1.

As can be further seen in FIG. 1, the fluid pressure regulator 38 is connected on the inlet side via a valve 57 to a conduit 58 in which a constant air pressure must be established. The fluid pressure regulator has the following problems.

This means that, in a known manner and in the form of a pressure reducer, a defined air pressure is reduced in proportion to the regulating force produced by the surge motor 39 and between the fluid pressure regulator 38 and the actuating device 24. pressure hose 36
The challenge is to apply low, regulated air pressure to the air.

Before the start of winding, the adjustment members 42, 43, ++# are adjusted by a certain number of parameters. In the adjusting element 42 an adjustment is made with respect to the specific gravity of the winding 13 and in the adjusting element 43 with respect to the selected length of the winding 13, and in the adjusting element 44 the friction area of the entire winding device is also determined. In addition, the friction value of the braking device is adjusted. The length of the winding is usually the same as the mutual spacing of the winding beam flanges and the same as the width of the thread group 14. The adjustment members 45 and 4-6 are continuously adjusted by the computer 521IC during the winding process, or
Or it will be corrected. The braking force adjustment device 37 uses a surge motor 39 to constantly adjust the fluid pressure regulator 38 to an accurate value during winding. Valve δ2 is still closed for the time being. The actuation device 24, the transmission device 23, and the brake 22 are
It's not working yet. The individual incoming threads of thread group 14 are monitored. If the thread tension relaxes for any reason, valve 57 opens.

Depending on the requirements of the fluid pressure regulator 38, the actuating device 24 is loaded with a more or less high air pressure and the brake 22 is activated.

A mechanical braking force adjustment device 59 is shown in FIG. 2 as another example of M-911. The device has a mechanical addition gear 60 as its central part.

The addition transmission 60 has length-adjustable adjusting members 61 to 6δ.
The joint members support each other and their overall length is defined by a measure for the braking force to be adjusted. The length-adjustable adjusting members 61 to 64 each consist of a nut and a bolt that are rotatable relative to each other. Thus, for example, the adjusting member 61 has a felt 66 and a bolt 70. The bolt 66 has a center hole into which a support bundling 74 is inserted. Bolt 66 is slidably and pivotably mounted on rod 80 using a bearing bush 74 . Bar 8

The nut 7o has an anti-rotation device 83 consisting of a groove, in which a guide pin 88 connected to a yoke 81 engages. The bolt 66 further has a drive gear 93, which is configured as a chain wheel that is mechanically and remotely adjusted from the pincushion.

Similarly, the throat 67 of the adjustment member 62 has a central bore into which a bearing bushing 75 is inserted;
By means of this bearing bush, the double door is also slidably and rotatably mounted on the rod 8o. The bolt 67 supports a drive gear 94 consisting of a chain wheel. The associated nut 71 is equipped with an anti-rotation device 84, in which:
A guide pin 89 coupled to the yoke 81 is engaged.

The bolt 68 of the third length-adjustable adjusting member 63 also has a central hole in which a bearing bushing 76 is inserted.

longitudinally slidably and rotatably supported thereon.

The bolt 68 supports a drive gear 95 consisting of a chain wheel.

Further, the Daltoro 9 has a center hole, and a support bushing: 5-77 is inserted into the center hole, so that the bolt 69 is also rotatably supported on the rod 8o so as to be slidable in the longitudinal direction. has been done. The associated nut 73 has an anti-rotation device 68 in which a guide pin 91 connected to a yoke 81 engages.

The next adjusting member 65 is of some material design. This adjustment member has a bushing 98 slidably and rotatably arranged on the rod 80, which bushing is connected to the drive gear 9.
7 is supported.

The drive gear 97 is again designed as a chain wheel for mechanical remote adjustment. Furthermore, the bushing 98 has an edge region 100 with a cam track 99 , in which a tracing roller 101 is supported, which tracing roller itself can slide on the bar 80 . However, it is connected to a shaft 102 which is supported in a non-rotatable manner. The bushing 102 has a central hole into which the bearing bushing 79 is inserted. The rod 80 fits exactly into the bearing bush 79. The bushing 102 has an anti-rotation device 87 consisting of a groove in which a guide pin 92 connected to the yoke 81 engages. Furthermore, the bushing 102 has a cylindrical part 103 which is longitudinally slidably supported in a bearing block 104, which for this purpose has a bearing bush 105.

From the bushing 102 there is a operative connection to a fluid pressure regulator 38, generally designated 106. This working connection consists of a lockable adjusting screw 107, a screw 108 and a driven roller 109. The renos 108 are supported on the yoke 81 using rotational hinges 110.

One end of the leno is in contact with an adjusting screw 107 on one side and a tensioned push spring 111 on the other side. The driven roller 109 is in contact with approximately the center of the rollers 108. The driven roller is held by a support 112 which is connected to the adjustment portion 11 of the fluid pressure regulator 38.
It is combined with 3. The fluid pressure regulator 98 itself also has a pressure spring, which is not shown in this case.

The pressure spring of the fluid pressure regulator 38 ensures that the driven roller 109 is always in contact with the reno 108.

The individual length-adjustable adjustment members 61 to 66 are supported one another and on the yoke 81 by axial or angular bearings. A total of five axial bearings are provided, which are of similar construction and are therefore all given the same reference numeral 114.

The axial bearing 114 is designed as a ball bearing.

The tensioned pressure spring 111 acts in such a way that no axial play occurs even if all adjustment members are adjusted to their shortest length.

The pressure spring also serves in particular to ensure that no axial play occurs in the nut-screw mechanism of the length-adjustable adjustment member. The free end of the rod 8o is supported by the yoke 81 via a bearing block 104 and a bushing 1o'2, as is clear from FIG. The nut-screw mechanism is self-locking, so that once an adjustment has been made, it remains in place unless externally manipulated.

The chain from the drive gears 93, 94.95 is pliers &-
It is guided to a steering wheel located in the wheel, of which only the chain 154 is shown in the drawing, on which manual adjustments can be made.

From the drive gear 97 a chain, again not shown, leads to a detection device for the winding diameter.

To start the winding process, first of all, the friction value of the braking device, including the direct friction of the entire winding device, is manually adjusted to the drive wheel 9.
It is adjusted to 6. The indentations in this case facilitate adjustment. Furthermore, on the driving wheel 96 and on the nut 73,
Markings are provided to facilitate adjustment. Once the adjustment has been carried out correctly, it is only necessary to adjust the adjustment after relatively large time intervals. The winding speed selected by the drive gear 93+'+ is then determined by the pincer gear, the particular gravity of the winding or thread group is determined by the drive gear 94, and the winding speed selected by the drive gear 93 is determined by the drive gear 95. The lengths that have been adjusted are adjusted accordingly. At the start of winding, the drive gear 97 is brought into a neutral position which can be controlled by the pointer 1'15. cam orbit 99
is formed empirically or computationally as follows. This means that as the winding diameter increases, the braking moment portion associated with it follows a precise course in relation to the selected braking time, i.e. first of all the winding becomes larger K
, and then increases approximately according to a function of e. Should the winding requirements change, the edge area 100 of the bushing 98 can also be replaced;
As a result, it is possible, for example, to always use a cam trajectory that is adapted to the selected braking time.

In the third embodiment shown in FIG. 3, many of the parts already described in the first embodiment shown in FIG. 1 are provided. FIG. 3 thus shows, for example, a warping machine 11, which in particular has a winding beam 12, said winding beam already having a roll 13 of fiber material, which fiber material In the form of a thread group 14, it is wound up via a measuring roller 15 and a deflection roller 16.
The take-up beam rotates in the direction of the curved arrow 17.

Unlike the first embodiment shown in FIG. 1, in this case the rotation speed detector 49 and the winding speed detector 51 are
16, and an output voltage proportional to the braking moment is applied to the output conductor 117 of the computer.

A collection rail 118 is provided to accommodate a certain JR parameter, and a certain DC voltage is applied to the collection rail. A total of five adjustment members 119 to 123 consisting of potentiometers are connected to the collecting rail 118. The output lead of the potentiometer is the calculator 11
6 & c I was guided and lied.

Before the start of winding, a certain noclameter is adjusted in the adjusting members 119, 120, 121 and 122.

Adjustment member 11O#>The adjustment of the specific gravity of the winding body 13 is
In addition, an adjustment for the selected length of the winding body 13 is carried out in the adjusting element 120, in addition the adjustment element 121 has the desired braking time, and the adjusting element 122 has the friction of the entire winding device. The friction values of the braking devices, including the braking devices, are respectively adjusted.

Adjustment member 123 remains unused.

All winding parameters are entered as electrical values in the calculator so that, according to the corresponding programming, the calculator can calculate the winding diameter, winding acceleration or winding delay, winding force, etc. in a known format. To detect the moment of inertia and braking moment of the beam, braking moment) K
A proportional voltage can be detected and transmitted.

7 consists of a pneumatic piston-cylinder mechanism, which is pivotably mounted on the silt 138. 138 is connected to the side wall 20.

From the actuating device 1''27 a pressure hose 139 is led to a braking force regulating device, designated in its entirety by the reference numeral 140 in FIG.
He is wearing number 41.

Braking force adjustment device 140 works mechanically. The braking force adjustment device 1 has a mechanical addition transmission 142 as its central part. The addition transmission 142 consists of longitudinally adjustable adjusting members 143 and 144, which are mutually supported and whose overall length forms a measure for the braking force to be adjusted. . The longitudinally adjustable adjusting members 143 and 144 each consist of a nut and a gel, which are rotatable relative to each other. Thus, for example, the adjusting member 143 may be

The support bushing 145 has a center hole into which a support bushing 147 is inserted. Support bushing 3.147
The felt 145 is slidably and rotatably supported on a rod 148.

The rod 148 is connected to a stationary yoke 149 which also supports a tongue 150 to which a fluid pressure regulator 141 is secured. The nut 146 has an anti-rotation device 151 consisting of a groove, in which a guide pin 152 connected to a yoke 149 engages. The shield 145 further includes a drive gear 153, and the drive gear is a pair of pliers. - It is configured as a chain wheel for mechanical remote adjustment from P.

By means of a synchronizer 154 consisting of a roller chain, the drive gear 153 of the adjusting member 143 is connected to the drive gear 93 of the adjusting member 61 of the adding gear 60 (FIG. 2).
As a result, the two adjustment members can be adjusted simultaneously and synchronously from the pliers.

The next adjusting member 144 has a bolt 155 with a drive wheel 156 consisting of a notched wheel for manual adjustment. Additionally, the seat 155 has a central hole into which a bearing bushing 157 is inserted, so that the seat 155
55 is also longitudinally slidably and rotatably supported on rod 148. The associated oak 158 has an anti-rotation device 159 in which a guide pin 160 connected to the yoke 149 engages.

The nut 158 is connected to a bushing 161 slidably mounted on the rod 148; the bushing 161 has a central hole into which a bearing bushing 162 is inserted. Rod 148 fits exactly within bearing bush 162.

Furthermore, the bushing 161 is slidably attached to the support block 1 in the longitudinal direction.
63 and the bearing block has a bearing bush 164 for this purpose.

The pressure spring of the fluid pressure regulator 141 acts so that the driven roller 168 is always in contact with the rollers 167.

Individual longitudinally adjustable adjustment members 143 and 144
are supported by axial or angular bearings K and yoke 149, which bearings are similarly constructed and are therefore designated by the same reference numeral 173.

The axial bearing 173 is configured as a ball bearing.

The tensioned push spring 170 is used even if all adjustment members are at most 1. Even if the length is adjusted to a longer length, there is no axial play at all.

The compression spring serves in particular to ensure that no play occurs in the nut-screw mechanism of the longitudinally adjustable adjustment member.

The free end of the rod 148 is supported by a yoke 149 through a support block 163 and a bush 161, as shown in FIG. The nut/screw mechanism has a self-locking effect, so that the adjustment made directly remains in place as long as it is not manipulated from the outside.

To start the winding process, the detected friction value of the braking device, including the friction area of the measuring roller 15, is manually adjusted to the drive wheel 156. In this case, the notches facilitate the adjustment. , the drive wheel 156 as well as the nut 158 are marked to simplify the adjustment.Once the adjustment has been made accurately, it only needs to be adjusted again at relatively large time intervals. From then on, the winding speed selected by the drive gear 153 is adjusted.

As soon as the desired adjustment has been made to the braking force adjustment devices for the winding beam 12 and for the measuring roller, 15, the winding process can begin.

Numerous embodiments of the invention are possible, and embodiments according to the invention using electrical components are particularly advantageous in terms of reasonable cost, weight and space requirements. In contrast, the robustness and operational reliability of purely mechanical control systems is comparable. However, the invention is not limited to the illustrated embodiment;
