Definitions

  • the invention relates to a textile machine (eg a card) with a working element in the form of a garnish that significantly affects the quality of the product of the machine, but whose condition deteriorates with increasing operating time (eg because of wear), which has a corresponding effect on the Product quality.
  • the textile machine is provided with a grinding system which can be used during machine operation to counteract the deterioration of the condition of the clothing.
  • a textile machine (namely a card) of the type described above is in EP-A-322637 shown. Since it has been proposed that the maintenance means should be constantly in use to constantly achieve the optimum quality. "Permanent” is to be understood in the sense that a grinding system or device is installed in the machine and therefore always ready for operation (even during operation of the machine) and not that is continuously ground during operation.
  • EP-A-497 736 can be done either during operation, ie during carding, or after the card has left the card.
  • the waiting times between the grinding periods must be determined empirically.
  • EP-A-004 186 describes a sander that can be attached to a card when it is necessary to grind a roll of the machine.
  • the device comprises a carrier and a unit which is movable back and forth on the carrier. The document deals on the one hand with the attachment of the device to the card and on the other hand with a construction of the unit, which favors the replacement of the grinding element.
  • This invention sets itself the goal of using systems EP-A-322637 more flexible, so that the capabilities of the system can be adapted to the requirements of the use.
  • Fig. 1 shows only the surface 12 of the spool 10. On this surface 12 is a set (not shown) mounted, which is equipped with teeth and thereby has a predetermined peak density (number of tips per unit area). This is indicated for only a part 14 of the spool surface - but the spool is equipped with tips over its entire working width AB. In operation, the drum rotates about its axis (not shown), which indicates a movement of the teeth in the direction of the arrow P.
  • the grindstone 16 after EP-A-497 736 is shown in its end position L
  • the aforementioned sensor is shown at 18.
  • a drive motor 20 and a drive transmission means (not shown, for example, a belt, the rail of a linear motor, a threaded spindle, etc.) and a holder (not shown) for the stone 16
  • the stone 16 in a direction perpendicular to the direction of movement P on the whole working width AB are moved.
  • the drum continues to spin.
  • the dimension of the grindstone in its own direction of movement and its speed of movement can be selected in such a way in comparison with the movement speed of the clothing teeth in the direction P that during a stroke movement of the grindstone from one side to the other of the spool each tooth of the set several times (eg 4 to 8 times) in Contact with the whetstone comes.
  • a single stroke (from one side of the spool to the other) is sufficient to "grind" all teeth, ie to exert a certain abrasive effect. If this abrasive effect is considered sufficient for certain purposes (as described below), a second layer L2 can be provided on the side of the spool away from the end position L, where the grindstone 16 can remain without touching the clothing. waiting point).
  • the system defines a "work cycle" consisting of an operational phase and a standby or waiting phase.
  • the operating phase begins and ends in or an end position (waiting point) - it accordingly contains a predetermined number (at least one) stroke movement from side to side of the working width.
  • the duration of the operating phase depends on the number of strokes and the speed of movement of the grindstone.
  • the duration of the standby phase is determined according to the criteria described below.
  • Fig. 2 schematically shows the spool 10, briseur 22, pickup 24 and the grinding system, which is indicated as a whole by the reference numeral 26.
  • the system 26 includes the grindstone 16 (FIG. Fig.1 ), its holder (not shown), the drive motor 20 (FIG. Fig. 1 ) and the guide means (not shown) which guides the grindstone holder during a lifting movement.
  • Fig. 2 also shows the drive motor 30 for the card, which sets the spool 10, for example via a toothed belt 32 in rotation when the card is in operation.
  • the motor 30 is controlled by signals from a card control 34 and returns its status to this controller 34 back.
  • Card control 34 also controls grinding system 26, in the illustrated example assuming that the grinding system is provided with its own "sub-control" 36 which autonomously performs certain control functions based on control commands from main controller 34.
  • the main controller 34 is provided with a display 38 and a keyboard 40 for human-machine communication.
  • This controller 34 also includes a timing signal generator, indicated schematically at 42.
  • each operating phase must include a certain number of Doppelhube (floats) from the end position.
  • Fig. 3 is a timing diagram and is used to explain the duration of the standby or waiting phase. This diagram is not to be understood as a realistic representation of reality but as a purely fictional diagram for explaining principles.
  • Fig. 3 the time is plotted on the horizontal axis and the tooth wear on the vertical axis.
  • the "curve” K1 represents the increasing tooth wear during a period T1 of uninterrupted operation with a given spool speed and a certain processed material.
  • the “wear” is here to be understood as tooth wear, which leads to an impairment of the functioning of the tooth as carding. This will be explained in more detail below on the basis of FIG. 4 explained. In other operating conditions (spool speed, processed material) the wear is slower (eg after the curve K2) or even faster (not shown), resulting in a steeper curve.
  • the operating time t (without use of the grinding system) is equal to the readiness period of the grinding system 26. During this period, the grindstone waits in its end position or is ready for use in this end position.
  • the time t can be entered by the operator via the keyboard 40 in the controller 34 (and retrieved via the display 38 back to the control). Through test settings, the "optimal" conditions can first be determined and the determined values can then be hard-coded for normal operation.
  • the duration of this waiting period will often prove to be a function of the total operating time of the clothing.
  • This may be taken into account by the controller 34 by means of an operating hours counter (not shown) and messages from both the engine 30 and the time signal generator 42.
  • the motor 30 (which drives the spool) is shown only as an example as a source for the signals driving the hour meter. Such signals could e.g. be removed from the customer drive and would thus have a closer relationship to the material flow.
  • the correct function of the operating time and a start signal after re-entangling must be entered by the operator, whereafter the controller 34 is able to determine the correct times for the use of the grinding system.
  • the controller 34 sends a start signal to the sub-controller 36 to initiate the use of the grinding system.
  • Fig. 4 shows diagrammatically two teeth 50, 52 of a clothing and the direction of movement P (see also Fig. 4 ).
  • the work of the tooth is done to the top S and the wear at this point is decisive for the product quality.
  • the technology of carding depends on the sharpness of the tip on the leading edge of each tooth 50, 52 and so on.
  • the tooth height is reduced to restore a sharp tip S1, S2, etc. at the leading edge during each grinding operation. This can be continued up to a very low tooth height, for example up to the tip Sn ( Figure 4 ), where the tip is in the transition to the next tooth.
  • the duration of the grinding operation or the necessary labor input depends on the tooth height, ie on the tooth cross-sectional area, which has to be machined during grinding. This area is a function of length 11, 12, 13, etc., ( Figure 4 ), which increases with each grinding operation. As previously indicated, each grinding of a given set results in a subsequent period of operation without loops, the duration of this period decreasing with the number of grinding operations performed. Therefore, with "classic" sanding (without a built-in sanding system), the work normally does not pay off long before the tooth height has been reduced to the theoretical minimum value.
  • an increase in the amount of labor required to perform a sequence of grinding operations can be realized by a corresponding increase in the number of strokes per grinding operation (and still without production interruption).
  • the system only finds its limit, where it must be constantly driven into operation with minimum operating speed (and / or with maximum adjustable contact pressure).
  • the number of strokes per operating phase and the change with the total operating time of a given set can also be entered by the operator via the keyboard 40.
  • the number of movements per grinding operation is then forwarded by the controller 34 to the controller 36 as a control command.
  • the engine 30 (or its “local” controller) is designed to operate at discrete preset speeds, it is possible to switch from the (or a) production speed to a "grinding speed". If the speed of the motor 30 is continuously adjustable (e.g., by means of a frequency converter) within predetermined limits, the controller 34 determines an output frequency of the converter which gives a suitable grinding speed of the spool.
  • the controller 34 Since the speed of a spool (because of its inertia) can not be changed immediately, at most a predetermined time delay from the controller 34 between the "switching" of the motor 30 and the use of the grinding system 26 must be inserted. If the speed of the motor 30 is monitored and reported to the controller 34, the controller 34 may be programmed so that it does not control the use of the grinding system until the Grinding speed of the motor 30 is reached.
  • Fig. 5 shows a modified arrangement that can work as a self-adjusting machine. Because the machine itself (along with its built-in grinding system) opposite Fig. 2 has not been changed, the machine parts and the system 26 (with its "local" controller 36) are indicated by the same reference numerals in both figures.
  • New in Fig. 5 is a sensor (or sensor assembly) 54 that checks (or which) the product 56 of the card 40.
  • the (or each) sensor 54 responds to a quality parameter that depends on the condition of the clothing 12 (FIG. Fig. 1 ) depends eg on the number of Nissen.
  • a Nissensensor for use in the output of a card is eg from DOS 3928279 or CH 669401 (respectively. US 4953265 ) known.
  • the quality sensor could face the spool or pickup, i. check the quality of the product directly on the rotating machine element (number of noses, for example).
  • a brightness sensor could, for example, be carried by the spool carrier in order to measure the brightness of the continuous clothing surface, this brightness changing with tooth wear.
  • a proximity sensor that responds to the distance to the teeth could serve a similar purpose.
  • the output of the sensor (or sensor array) 54 is provided to the card control 34A.
  • This control is different from the controller 34 (FIG. Fig. 2 ) only by the control program, which is tailored to the application in combination with the quality sensor or ZahnSullivanssensor.
  • the Nisseniere Ao ( Figure 6 ) represents a lower limit, which can be achieved with a new set in the optimum state. After restarting the material processing (at the time to) with this new set, the number of nits increases as the garniture condition deteriorates due to wear of the teeth.
  • the number of noses Ag represents a limit value for the user (for the spinning mill), which must not be exceeded without intervention.
  • the instantaneous number of nits (the actual value) is reported by the sensor (or sensor assembly) 54 to the controller 34A. As long as the actual value is below the limit value Ag, the whetstone 16 remains Fig.1 ) of the system 26 in the waiting position (standby phase). At time t1, however, the sensor 54 reports the reaching of the limit value Ag and the control accordingly triggers an operating phase of the system 26 (control command to the local control 36).
  • the controller 34A then outputs eg via the display 38 (FIG. Fig.2 ) an alarm, so that at a suitable opportunity, the re-tumbling of the drum can be performed.
  • the invention is not limited to the application to the spool set. It is also not limited to an arrangement whereby the grindstone is moved from side to side of the working width.
  • Fig. 3 the aforesaid EP 322637 shows an arrangement according to which the abrasive extends over the entire working width. The arrangement is particularly advantageous for grinding flat clothings (flexible clothings).
  • Such a system may also be controlled in accordance with the present invention by having the abrasive in the standby position at a radial distance from the clothing. A moving means may then be provided to move the abrasive in the radial direction from the ready position to the operating position (in contact with the clothing).
  • grindingstone in this context means a grinding element which is suitable for grinding a clothing, irrespective of which material the element is formed (for example ceramic or sintered metal).
  • the control of various "speed profiles" across that width can be effected.
  • the moving speed of the element is kept constant, but this speed can be changed over time (with increasing operating hours since the last grinding operation) or be adjustable.
  • the operating speed may also be changed as a function of the distance from or from a waiting location, e.g. so that the speed reaches a maximum value in the middle between two waiting points.
  • Fig. 7 schematically shows a single tooth 60 and the grindstone 62.
  • the arrow 64 shows the direction of rotation of the spool or of the tooth 60 during production. The grinding during further production inevitably leads to "grinding against the tooth", ie the leading edge of the tooth hits the grindstone first.
