Abstract:
A position detection device includes: a first group including N (a multiple of 3) first magnetic sensors facing a magnet that rotates in synchronization with a rotation shaft of a motor and arranged at intervals along a rotation direction of the magnet, and a second group including N second magnetic sensors arranged opposite respectively to the N first magnetic sensors across the rotation shaft in a radial direction of the magnet; and a signal processing device processing output signals respectively output from the first and second magnetic sensors. The signal processing device executes averaging processing of generating N average signals by averaging an output signal of the first magnetic sensor and an output signal of the second magnetic sensor arranged at the position opposite to the first magnetic sensor across the rotation shaft, and estimation processing of estimating a rotational position of the motor based on the N average signals.
Abstract:
A textile production monitoring system includes an electronic device connected with a sewing machine, and with sensors connected with the knife, the pedal, the motor tach of the sewing machine, and with the needle, the sensors transmitting signals to the electronic device. A microprocessor evaluates the four signals received from the sensors in a coordinated way. A software possessing a four-signal algorithm generates information about the products, information on which operator works on which machines for how long, how much product they produce, failure status, and machine efficiency. An Rfid module is connected with the electronic device for monitoring the information and working status of the personnel working on the sewing machine. At least one barcode reader allows for entering information on which order the product sewn in the sewing machine belongs to. A wireless connection module facilitates transfer of the information from the electronic device and the microprocessor wirelessly.
Abstract:
Apparatuses, methods, and computer program products for quilting webs without compressing the webs. A quilting machine includes a needle bar to which needles are attached, needle thread passing through each needle, a looper shaft to which loopers are attached, a looper corresponding to each needle and from which looper thread is provided to form stitches, and a retainer bar to which spreaders are attached to facilitate stitching. A drive pulley powered by a first servo motor rotates cranks to move the needles through a cycle and rotates a belt which rotates an indexer pulley. Rotation of the indexer pulley oscillates the looper shaft and reciprocates the retainer bar. Another drive pulley powered by a second servo motor operates to move an input web through the machine between chain stiches.
Abstract:
A processing data generation device includes a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring processing of acquiring a pattern represented by a contour, division processing of dividing the pattern into a plurality of pattern pieces, and offset setting processing of setting an offset line disposed at a position separated to an outside, from an adjacent portion, by a predetermined distance. The processes include processing line setting processing of setting, for each of the plurality of pattern pieces, a processing line including the offset line and surrounding a pattern piece and processing line processing of generating processing line processing data, for each of the plurality of pattern pieces, for processing a sheet-shaped workpiece along the processing line, using a processing device configured to perform processing on the workpiece.
Abstract:
The present invention provides a system and method for the application of a functional thread to secure roving or other fibers to a substrate, thereby forming a precursor to a resultant composite component structure having targeted, enhanced structural reinforcement. The functional thread may be comprised of one or more fibrous filaments or have a monofilament structure. The invention encompasses the sewing of this functional thread at varying stitch densities as function of component stress analysis, the mechanical stresses that the component will be subject to when exposed to the forces and loads associated with its intended use, and at least one physical or mechanical property of a functional thread. This variable stitch density serves to provide targeted, localized mechanical enhancement and reinforcement to the resultant composite structure.
Abstract:
A sewing machine includes a carriage, a storage portion, a display portion, and a control device. A plurality of types of an embroidery frame is configured to be removably mounted on the carriage. The embroidery frame is capable of holding a work cloth. The carriage is capable of moving the embroidery frame parallel to two intersecting axes. The storage portion is configured to store a plurality of sizes of the work cloth that respectively correspond to the plurality of types of the embroidery frame. The display portion is configured to display information relating to at least sewing. The control device is configured to read, from the storage portion, the sizes of the work cloth that respectively correspond to the types of the embroidery frame. The control device is also configured to cause the display portion to display the sizes of the work cloth that have been read.
Abstract:
A punch data generating device generating punch data for execution with an embroiderable sewing machine including a needle bar moved up and down and mounted with a punch needle for forming penetrations on a workpiece in dot-by-dot strokes, a transfer mechanism transferring the workpiece in two directions in coordination with the movement of the punch needle to form the penetrations. The punch data generating device includes a cut data generator generating cut data constituting the punch data, the cut data being used to form the penetrations along an outline of a predetermined pattern to allow cutting of the outline; and an auxiliary cut data generator generating auxiliary cut data constituting the punch data, the auxiliary cut data being used to form penetrations contacting the outline of the pattern to form a cut that facilitates detachment of the outline from the workpiece.
Abstract:
A sewing data converting device includes a storage means for storing sewing data used in one embroidery machine for executing a sewing operation including an embroidering operation. The sewing data is converted into another sewing data used in another embroidery machine having a data format differing from one of the one embroidery machine. Display data for the converted sewing data is originated so that the display data corresponds to a display format of the another embroidery machine.
Abstract:
All embroidery data in a flash memory card are copied to a RAM, and file numbers of the embroidery data copied to the RAM are displayed on a LCD. When the user selects the embroidery data to be erased, the data are erased from the RAM and the LCD. When the selection of the data to be erased is over and an end key is pressed, the flash memory card is initialized, and thereafter the remaining embroidery data left on the RAM are copied to the flash memory card. Accordingly, the operation of rewriting the data in the flash memory card is completed at one time, with the result that the rewriting time required for the erasing of plural embroidery data can be greatly reduced.
Abstract:
A sewing data forming device which forms sewing data to form a fine seam merely by inputting the coordinate data of a plurality of points on a free curve which includes the start and end points. The sewing data forming device for a sewing machine comprises data input unit for inputting coordinate data of a plurality of points along a sewing pattern, the data input unit designating an input condition among point input, linear input and curve input, data storage unit for storing data inputted by the data input unit successively, and data processing unit for applying inclination data to each of the coordinate data so as to form the sewing data between the points adjacent to each other according to a stitch length specified for an interval therebetween.
