Drum intermediate storage device for a textile machine
The invention relates to a drum intermediate storage of yarn for a textile machine having a driven rotary drum with a working surface and a movable radial rotary arm. The driven rotary drum is coupled with a first drive and the arm is coupled with a second drive, whereby both drives are composed of motors and both motors are connected to a control system of the textile machine. The radial rotary arm is provided with a yarn guide, whose working portion upholds the yarn radially relative to the axis of rotation of the drum.
YARN FEEDER WITH MOTORIZED YARN WINDING SPOOL
A yarn winding assembly installed on a support includes a motorized spool and an oblique spacer pin, between which a yarn is wound. The spacer pin is supported rotatably by a rotating supporting component so that it is entrained in two directions by the yarn wound between the spool and the spacer pin. The rotation of the spacer pin is delimited by an element of arrest at least in a direction of unwinding the yarn.
DEVICE AND METHOD FOR AUTOMATICALLY CHECKING THE QUALITY OF A SPOOL OF THREAD FOR FABRICS
A device for automatically checking quality of a spool of thread for fabrics is provided. The device has at least one vision system provided with a camera, a frame of the camera defining an analysis area, the camera being connectable to a system for moving a spool of thread to be analyzed and to a computer having an analysis software stored thereon, and at least one lighting system having at least one pair of lights arranged facing each other and transversely in relation to the analysis area, each light of the at least one pair of lights having at least one light source for providing a sidelight to the analysis area.
Compact device for controlling the supply of thread to a processing machine
A compact device for controlling the supply of a textile or metal thread to a processing machine, such as a textile machine or a spooling or winding machine, includes a body, at least one rotary member with which the thread cooperates, the member associated with a rotation velocity detector for detecting the rotation velocity thereof, the detector connected to a control unit, a tension detector provided for detecting the thread tension connected to such control unit. The rotary member is idle and is placed in rotation by the thread which is moved thereon, in proximity to such member the tension detector being placed. Also disclosed is a method for controlling the supply of thread actuated by such device.
Method and winding station for improving a winding process of a textile machine
A method improves a winding process of a textile machine and a winding station of a textile machine having a machine controller (11), a yarn sensor (4), a yarn quality monitor, in particular a yarn clearer (5), and a yarn connecting device, in particular a splicing device (3). A yarn (1) is wound onto a bobbin (2). The yarn (1) is analyzed with regard to its length, quality, and/or speed, and is cut if necessary in order to clear a quality defect and two yarn ends are connected to one another by means of the yarn connecting device after the quality defect has been removed. The yarn (1) is analyzed with regard to foreign material, yarn speed, and/or yarn length by means of a capacitive yarn sensor (4), and is analyzed with regard to the yarn body and the yarn characteristic by means of an optical yarn quality monitor. The yarn (1) is subsequently optionally cleared. Data of the capacitive yarn sensor (4) with regard to the foreign material and/or the yarn speed is provided to the yarn quality monitor, in particular the yarn clearer (5), and with regard to the yarn length and/or the yarn speed are provided to the machine controller (11).
Multi-spool threader
A spool of thread holder and threading device for holding a plurality of spools of thread, made up of a frame and a plurality of spool thread holders, said spool thread holders further comprising a rod, a base and a wing. The wing attaches to the rod along the axial length of said rod and the rod extends from the base. Each of the individual spool thread holders comprising the multiple spool thread holder, allows receipt of a spool of thread and the wing maintains the spool of thread adjacent the base. The frame is configured for attachment to a quilting machine to allow thread to unspool from each non-rotating spool of thread during operation under substantially equal tension.
Method for determining operating conditions of a textile machine, and a textile machine
A method is provided for determining a functional status at a workstation of a textile machine that includes a plurality of the workstations, wherein each workstation includes at least one drive associated with a treatment device configured at the workstation to treat a fiber material. The method includes measuring a load variable of the drive and determining the functional status of the treatment device based on the measured load variable.
Method and system for feeding a thread to a textile machine, at a constant tension and preset draw, as a function of the operating step of the latter
A method for feeding a thread at a preset drawing to a textile machine includes a first feeder which sends the thread to the textile machine and a second feeder arranged spaced from the first feeder and which sends such thread to the latter, each feeder having a rotary member on which there is partly wound the thread before the feeding thereof and a speed sensor adapted to detect the rotational speed of such rotary member and a tension sensor to detect the tension of the thread exiting from each feeder. Controlling drawing the thread sent to the textile machine by controlling and adjusting the ratio between the rotational speed of the rotary member of the first feeder and the rotational speed of the rotary member of the second feeder.
WINDING MACHINE
A winding machine (1) for a traversing application of a winding material (51) to a spool sleeve (27) comprises a spindle (8) which is supported for being rotated and for having a fixed axial position. The spindle (8) comprises an inner recess. The winding machine (1) comprises a drive driving the spindle (8) for a rotational movement and a traversing carriage (20). The traversing carriage (20) is supported on the spindle (8) for being movable with a traversing motion (18) in an axial direction relative to the spindle (8). A first coupling element serves for transmitting the rotational movement of the spindle (8) to the traversing carriage (20) and a second coupling element serves for transmitting the traversing motion (18) of the traversing carriage (20) to the spool sleeve (27). The winding machine (1) also comprises an actuation mechanism (30) executing the traversing motion (18). The actuation mechanism (30) is coupled to the traversing carriage (20) for transmitting the traversing motion (18) from the actuation mechanism (30) to the traversing carriage (20). The actuation mechanism (30) extends through the inner recess of the spindle (8).
