Definitions

  • the invention relates to a device for severing a thread that has two blades, at least one of which is movable relative to the other by means of an electric drive, and to a method for severing a thread.
  • a device for severing a weft thread for a weaving loom is known (German Patent Disclosure DE 2230099), which has two blades that are movable relative to one another. This device is located in the vicinity of the fabric edge, in order to cut off a weft thread that is picked up by a gripper and transported into the shed. To improve the cutting operation, the blades are pressed against one another by spring force. One of the blades is driven via a cam system, which in turn is driven by the weaving loom.
  • Such a device has the disadvantage that the speed of motion of the blades in cutting off the thread is determined by the speed of the drive means, whose speed is determined by the speed of the weaving loom.
  • a device of the type defined at the outset is also known (European Patent Disclosure EP 0284766 A1), which as its drive includes an electric drive motor.
  • this known device one problem is that the relative speed of the blades upon severing a thread is determined by the activating and properties of the electric drive means.
  • the object of the invention is to create a device of the type defined at the outset in which the speed of motion of the blades during the severing operation is independent of the speed of the weaving loom or of properties of an electric drive.
  • the at least one movable blade is movable by the drive counter to the action of at least one spring element into a ready position from which, by means of the force of the at least one spring element, it can be moved back again for executing a severing operation.
  • the invention offers the advantage that the speed of motion of the blades is independent of the drive means and can thus be selected as a function of the thread to be severed, in particular a weft thread of a weaving loom.
  • the speed of the relative motion between the blades is determined essentially by the natural frequency of the means that retain the movable blade and that move with the blade.
  • the application of the device according to the invention to weaving looms leads to the advantage that the speed of severing is independent of the weaving speed of the weaving loom and independent of the response times and reaction times of the electric drive means.
  • the speed for the cutting can be set adequately high in all cases to enable satisfactory severing of a weft thread. This is advantageous above all whenever the power loom is operated at slow speed, and a weft thread has to be severed or cut.
  • both blades can be moved into a ready position with contrary motion by means of electric drives and can be moved back again by means of spring elements.
  • substantially higher cutting speeds can be attained than with one stationary blade and only one moving blade.
  • the blade or blades are each retained by respective pairs of leaf springs, which are oriented transversely to the direction of motion of the associated blade and are disposed spaced apart from and parallel to one another. Since the blades need not execute excessively great motions, and since the leaf springs in turn can have a relatively great length, it is possible in this way to move the blades substantially rectilinearly, without having to provide guides for the purpose.
  • the blade or blades are connected to an armature which contains at least one permanent magnet and with which an electromagnet is associated.
  • both blades are provided with armatures in which the permanent magnets are arranged such that like poles face each other in the ready position and unlike poles face each other in the severing position.
  • the armatures and thus the blades attract one another while they are in the region in which the severing operation takes place. The cutting operation is thus improved.
  • the armatures and hence also the blades repel one another, however, while they are in the region of the ready position, and as a result wear to the blades moving relative to one another is reduced.
  • one common electromagnet is provided for the armatures of both blades; and the permanent magnets of the armatures are oriented in opposite directions.
  • the common electromagnet has the effect that upon its excitation, the two armatures are moved with their blades in opposite directions.
  • the two units comprising a blade, an armature, and leaf springs are designed for different natural frequencies.
  • the natural frequency can be defined. It is advantageous if the speeds of motion, selected by means of the natural frequency, are set so differently that the position in which the cutting is done differs from the position of repose when the electromagnet is not excited. It can thus be attained that in gripper looms, in a position of repose assumed when the electric drive means are not excited, the device is located above the fabric, so that upon beating up, the weft threads can pass underneath the device.
  • weft threads can be severed at the level of the plane of the fabric.
  • This mode of operation is made possible whenever the blade that is moving downward is faster than the blade that is moving upward.
  • the different speed and hence a different course of motion can be attained by providing that leaf springs of different stiffness or with a different spring characteristic curve, and/or armatures of different mass, and/or blades of different mass are used.
  • Each of these provisions contributes alone or in combination with other provisions to a change in the natural frequency.
  • a CAN bus system is provided for a control unit of the electric drive or drives.
  • the object is attained by a method in which the electric drive moves the at least one blade into a ready position counter to spring force, and for executing a severing operation, this blade is moved back again from the ready position at least by means of the spring force.
  • the electric drive is activated while the associated blade is being moved back from the ready position by means of spring force.
  • the speed and the course of motion during the severing can both be varied.
  • the electric drive brakes the associated blade during the motion back from the ready position, particularly after the severing operation has been performed.
  • a signal dependent on the motion of an armature of the electric drive is formed, by means of which the course of motion of the associated blade is monitored.
  • This signal which comprises a voltage, for instance, serves as feedback for controlling the device of the invention.
  • FIG. 1 shows a device according to the invention in a position of repose
  • FIG. 2 shows the device of FIG. 1 , with a few components having been left out to increase the clarity;
  • FIG. 3 is a vertical section through FIG. 2 ;
  • FIG. 4 shows the device of FIG. 1 (leaving out additional components) in a ready position
  • FIG. 5 shows the device of FIG. 1 in a severing position
  • FIG. 6 is a fragmentary view in the direction of the arrow F 6 of FIG. 1 .
  • the device according to the invention shown in FIG. 1 has two blades 2 and 3 , movable relative to one another, and electric drive means for moving these blades 2 , 3 relative to one another.
  • the blade 2 is connected to an armature 5 , which is retained movably by means of leaf springs 6 , 7 .
  • the blade 3 is connected to an armature 8 , which is retained movably by means of leaf springs 9 , 10 .
  • the leaf springs 6 , 7 and 9 , 10 are oriented transversely to the direction of motion of the blades 2 , 3 and are disposed parallel to and spaced apart from one another.
  • Each of two leaf springs 6 , 7 ; 9 , 10 are located directly one above the other, so that thin leaf springs, which are advantageous with respect to the service life, can be used.
  • the armatures 5 , 8 are each retained on both ends by relatively long leaf springs 6 , 7 ; 9 , 10 , so that the armatures 5 , 8 move essentially linearly.
  • the ends of the leaf springs 6 , 7 ; 9 , 10 remote from the armatures 5 , 8 are retained by means of a holder 11 in which they are fastened.
  • the leaf springs 6 , 7 and 9 , 10 are embodied in one piece in the region of the holder 11 , in this exemplary embodiment.
  • the holder 11 has a shaft 12 , which is mounted for instance by means of an arm 13 on a frame of a textile machine.
  • the shaft 12 is fastened between the arm 13 and a clamping element 14 and as a result can be disposed at an arbitrary axial or radial point.
  • the device according to the invention can be positioned relative to a textile machine in such a way that a thread can be severed or cut off. In this way, the device according to the invention can be disposed in a gripper weaving loom in the direction of the weft thread in a predetermined position relative to the fabric.
  • holder elements 15 are secured to the holder 11 ; they carry an electromagnet 16 , cooperating with the armatures 5 and 8 , and a control unit 17 .
  • the control unit 17 is connected to a control unit of the textile machine via a cable 18 .
  • the control unit of the textile machine sends signals to the control unit 17 for actuating the device 1 according to the invention synchronously with the textile machine.
  • each electromagnet 16 cooperating with a respective armature 5 or 8 , has two mirror-symmetrically disposed iron cores for the armatures 5 and 8 ; that is, two iron cores 19 for the armature 5 , and two iron cores 20 for the armature 8 .
  • the iron cores 19 , 20 are formed from plates.
  • a pair of coils 21 for the iron cores 19 , 20 is provided, so that both electromagnets 16 can be controlled by the same pair of coils 21 .
  • the coils 21 are each disposed around a middle part 22 of the iron cores 19 , 20 in the region of the armatures 5 , 8 .
  • the iron cores 19 , 20 are secured to the holder elements 15 by means of screws.
  • the iron cores 19 , 20 are embodied in one piece; that is, they comprise only one set of plates fastened together.
  • a housing 23 of nonmagnetizable material is disposed around the electromagnets 16 .
  • each electromagnet 16 that cooperates with one of the armatures 5 or 8 is controlled by its own coil.
  • two permanent magnets 24 , 25 are accommodated in the armature 5 and two permanent magnets 26 , 27 are accommodated in the armature 8 .
  • These permanent magnets 24 through 27 have a rodlike shape and have two poles.
  • the north-south direction of the permanent magnets 24 through 27 extend vertically to the direction of motion of the armatures 5 and 8 .
  • the permanent magnets 24 , 25 on the one hand and the permanent magnets 26 , 27 on the other are each disposed such that the unlike poles border one another.
  • Each of the permanent magnets 24 through 27 has a length equivalent to approximately the magnitude of the motion of the associated armature 5 or 8 between a position of repose, with the coil not excited, and a position with the coil 21 excited.
  • the permanent magnets 24 , 25 are oriented with their poles oppositely to the poles of the permanent magnets 26 , 27 , so that upon excitation of the coil 21 , the armatures 5 , 8 are each moved in opposite directions. Because of this embodiment, it is possible for both armatures 5 , 8 to be actuated with either the same coil 21 or with one coil set 21 .
  • the blades 2 , 3 are in a position of repose, in which the coil 21 is not excited.
  • the armatures 5 , 8 move in opposite directions as far as a position that is shown in FIG. 4 . This position is called the open position or ready position. In this position, the armatures 5 , 8 and thus also the blades 2 , 3 are moved counter to the force of the leaf springs 6 , 7 ; 9 , 10 .
  • the electromagnets 16 and the exciter current for the electromagnets 16 are understood to be adapted to the strength of the leaf springs 6 , 7 ; 9 , 10 , or else the leaf springs 6 , 7 ; 9 , 10 are adapted to the electromagnets 16 and to the exciter current. Since the like poles of the permanent magnets 24 , 26 on the one hand and the permanent magnets 25 , 27 on the other rest side by side in the ready position, the armatures 5 , 8 are pressed apart somewhat, so that the blades 2 , 3 are pressed against one another with only slight force.
  • a thread A to be severed or to be cut for instance a weft thread in the case of a gripper weaving loom, is placed between the blades 2 and 3 .
  • This can be done for instance in the way described in DE 2230099.
  • the armatures 5 , 8 are moved back again out of the ready position by the force of the prestressed leaf springs 6 , 7 ; 9 , 10 , so that they sever the thread A located between the blades 2 , 3 , in a cutting position that is shown in FIG. 5 .
  • the unlike poles of the permanent magnets 24 through 27 face one another, so that the armatures 5 , 8 attract one another, which reinforces the cutting operation.
  • the cutting position is located somewhat lower than the position of repose shown in FIG. 2 .
  • This is due to the fact that the blade 3 moves downward at a higher speed than the speed at which the blade 2 moves upward.
  • This difference in speed is due, in the embodiment shown, to a difference in the natural frequency between the unit comprising the blade 2 , armature 5 and leaf springs 6 , 7 and the unit comprising the blade 3 , armature 8 and leaf springs 9 , 10 .
  • the difference in the speed of motion is caused for instance by the fact that the unit having the blade 2 is heavier and thus moves more sluggishly than the unit having the blade 3 .
  • the coil 21 may also be activated.
  • the excitation of the coil 21 not be interrupted, but instead that a relatively low current be made to flow through the coil.
  • a current is passed through the coil 21 that is opposite the current that flows through the coil 21 for putting the blades 2 and 3 into the ready position shown in FIG. 4 .
  • the blades 2 , 3 during their motion out of the ready position, are likewise controlled by the electric drive means 4 .
  • the coil 21 is briefly excited after the cutting—for instance as described above—in other to brake the blades 2 , 3 . After that, the unit can settle freely until the position of repose of FIG. 2 has been resumed. The settling process is damped since the blades 2 , 3 rest on one another and rub against one another. In a modified version, damping is accomplished by the drive means 4 . To that end, the coils 21 can be short-circuited after the severing operation. The motion of the permanent magnets 24 through 27 generates a voltage which, with short-circuited coils 21 , generates a current through the coils 21 .
  • the control unit 17 of the device of the invention is connected via a cable 18 to a CAN bus system, so that the electric drive means, and in particular the coil 21 , can be activated via this CAN bus system.
  • control unit 17 is provided with means for detecting the course of motion of the blades 2 , 3 during the motion and in particular the cutting motion. This can be done for instance by measuring an electrical signal that occurs in the coil 21 as a result of the permanent magnets 24 through 27 , moving relative to the coil 21 , of the armatures 5 , 8 . On the basis of this signal, the instant of cutting can be determined. The determination of the instant of cutting can also be done in some other way, such as with the aid of optical sensors, or as known from International Patent Disclosure WO 99/29946.
  • this method can for instance be employed to compare the correct instant of cutting with the instant when the coil 21 is no longer excited.
  • the instant when the drive means 4 are no longer excited is synchronized with the weaving cycle by setting or adjusting the instant of the end of excitation within the weaving cycle such that cutting is done at the correct instant within the weaving cycle.
  • a correct setting of the instant of the end of excitation can be defined for every device for cutting, without there being any influence by the properties of the leaf springs, armatures or blades on the synchronization of the instant of cutting with the weaving cycle.
  • Such a setting can be achieved for instance by providing that the instant of the end of excitation of the coils 21 is set relative to the position of the drive shaft of the gripper weaving loom such that the armatures 5 and 8 , which are restrained firmly in their ready position, are released at that instant.
  • the relative instant of thread cutting relatively to the instant of the end of excitation can then be used as a feedback value for setting or adjusting the instant of the end of excitation relative to the position of the drive shaft of the gripper weaving loom.
  • the instant of cutting can be set precisely or changed by the control of the end of excitation as a function of the aforementioned, previously determined position relative to the position of the drive shaft and thus relative to the weaving cycle.
  • FIGS. 1, 3 and 6 details are also shown for how the blades 2 and 3 are connected to the armatures 5 and 8 .
  • the leaf springs 7 are secured to the armature by means of a clamping element 28 .
  • a T-element 30 is secured to this clamping element 28 by means of a screw.
  • the blade 2 is secured to this T-element 30 by fastening means 31 .
  • the leaf springs 10 are secured to the underside of the armature 8 by means of a clamping element 29 .
  • a T-element 32 is secured to this clamping element 29 .
  • a leaf spring 33 is secured to this T-element 32 by a fastening means 34 .
  • the blade 3 is secured to this leaf spring 33 by adhesive bonding, soldering, or welding, or the like, for instance.
  • adhesive bonding soldering, or welding, or the like.
  • the armatures 5 and 8 each have only one permanent magnet, for instance the permanent magnets 25 and 26 , respectively.
  • the permanent magnets 25 and 26 respectively.
  • Different speeds for the motion of the blades 2 and 3 can also be attained by providing that in the motion toward the cutting position, the blades 2 , 3 are controlled differently by the electric drive means 4 , by using permanent magnets of different strengths for the two armatures 5 , 8 , by activating the electromagnets 21 differently, by activating each armature 5 , 8 by a different electromagnet, or by a combination of these provisions.
  • an auxiliary coil may be provided for each armature 5 , 8 , in order to speed up or slow down the motion of the armature 5 , 8 during cutting.
  • the ready position is determined essentially by the longitudinal dimensions of the permanent magnets 24 through 27 .
  • this position can be determined with the aid of sensors, for instance optical sensors, that cooperate with the control unit 17 .
  • the control unit 17 may for instance control the current delivered to the coil 21 such that the armatures 5 , 8 assume a previously defined ready position.
  • the device of the invention is not limited to use in a gripper weaving loom. It can readily be employed in any other textile machine in which threads must be severed, such as air jet looms, gripper shuttle looms, water jet looms, projectile looms, other types of weaving looms, knitting machines, sewing machines, and other textile machines.
  • the device of the invention offers the advantage that it can be built into any existing textile machine without problems.
  • a particular advantage is that a thread can be severed at a relatively high cutting speed, which can be adjusted independently of the speed of the textile machine and independently or at least largely independently of the electric drive means. Because the two blades 2 , 3 move relative to one another upon cutting, a higher cutting speed is obtained compared to the case in which one of the blades is stationary.
