Patent application number | Description | Published |
20080216724 | Sewing machine, sewing mark, and computer-readable recording medium storing sewing machine control program - A sewing machine includes a needle bar to which a sewing needle is attached, a sewing machine motor that drives a needle bar mechanism for vertically driving the needle bar via a drive shaft, an information reading device, and a control device. The information reading device is disposed in the vicinity of a needle drop position of the sewing needle and reads out sewing information relating to sewing conditions for the sewing machine each time a mark attached to a work cloth enters into a communication range as the work cloth is moved, the sewing information being stored in an RFID tag included in the mark. The control device controls sewing based on the sewing information read out by the information reading device from the RFID tag. | 09-11-2008 |
20080223275 | Embroidery sewing system - An embroidery sewing system includes an embroidery data processing apparatus and a sewing apparatus. The embroidery data processing apparatus generates and processes embroidery data used to sew an embroidery pattern on a work cloth. The embroidery data processing apparatus includes an embroidery data generation device that generates embroidery data including pattern data for specifying a color and a shape of the embroidery pattern, and a data writing device that writes the embroidery data into an RFID tag attached to the work cloth. The sewing apparatus includes a sewing device that sews the embroidery pattern based on the embroidery data, a data reading device that reads out the embroidery data written into the RFID tag by the data writing device, and a control device that controls the sewing device based on the embroidery data read out from the RFID tag. | 09-18-2008 |
20090020054 | Embroidery data processor, embroidery sewing system, computer readable medium and multi-needle embroidery sewing machine - An embroidery data processor that processes embroidery data for sewing an embroidery pattern comprising a plurality of subset patterns on a workpiece cloth with different needle thread colors by using a plurality of multi-needle embroidery sewing machines each provided with an embroidery frame drive mechanism that moves an embroidery frame holding the workpiece cloth in two predetermined directions, the embroidery data processor including a sew-time calculator that calculates required sew time for sewing each subset pattern based on subset pattern data being classified by thread color; and an allocator that produces an allocation schedule for allocation of the subset patterns to the multi-needle embroidery sewing machines based on the sew time calculated by the sew-time calculator, the allocation schedule being arranged to distribute equal or minimally-different sew time for each multi-needle embroidery sewing machine. | 01-22-2009 |
20090205548 | Sewing machine and computer readable medium storing sewing needle status evaluation program - A sewing machine provided with a needle bar having a sewing needle interchangeably attached to its lower end including an imaging element that captures images of the sewing needle; an extractor that extracts a shape of the sewing needle from the images of the sewing needle captured by the imaging element; an abnormality determiner that determines presence/absence of abnormalities in measurements of the sewing needle based on the shape of the sewing needle extracted by the extractor; and an abnormality alerter that alerts the presence of abnormalities determined by the determiner. | 08-20-2009 |
20090266282 | Sewing machine and computer-readable medium storing sewing machine control program - A sewing machine includes a sewing device, an imaging device, a determination device, a sewing condition storage device, a reading device, and a control device. The sewing device includes a needle bar and a sewing machine motor. The imaging device captures an image of a work cloth on which a marker is disposed to identify information corresponding to actual sewing conditions. The determination device determines an appearance feature of the work cloth based on the image obtained by the imaging device. The sewing condition storage device stores the appearance feature and sewing condition information corresponding to the sewing conditions that are correlated with each other. The reading device reads the sewing condition information corresponding to the appearance feature from the sewing condition storage device. The control device identifies the actual sewing conditions based on the sewing condition information read out by the reading device, and controls the sewing device. | 10-29-2009 |
20100224111 | Sewing machine provided with needle bar rocking mechanism - A sewing machine includes a needle bar to which a needle is attached, a needle bar rocking mechanism which rocks the needle bar, a needle plate having a needle hole through which the needle is passed, an imaging device which images a lower part of the needle bar, a setting section which sets a range of rocking motion of the needle bar based on an image obtained by the imaging device, and a control device which controls the needle bar rocking mechanism based on the range of rocking motion set by the setting section. | 09-09-2010 |
20120060733 | SEWING MACHINE OPERATING DEVICE AND SEWING MACHINE PROVIDED THEREWITH - A sewing machine operating device includes a base, a connecting mechanism which electrically connects the sewing machine operating device to a sewing machine body, a plurality of operating members which is mounted on the base and operated by a user with his/her foot, a signal output unit which generates an operation signal and delivers the operation signal via the connecting mechanism to the sewing machine body, the operation signal being according to operation of each operating member, and a position adjusting mechanism which changes a position of at least one of the operating members mounted on the base. | 03-15-2012 |
