摘要： PURPOSE:To enhance the generating work efficiency of sewing data by providing a storage means in which external form line data of the cloth end of working cloth, sewing margin data and sewing pitch data are stored, so that an operation of a reference position and the number of needles can be executed automatically. CONSTITUTION:This device is provided with a storage means in which external form line data of the cloth end of working cloth, sewing margin data and sewing pitch data are stored, at the time of generating sewing data, in the case it is performed to a vertical differential sewing machine of a type for feeding the upper cloth UW and the lower cloth DW by each moving device 32, 46 for the upper cloth and the lower cloth. In such a state, based on data read out of the storage means, the number of needles A of a seam forming line to be formed in a position separated by a sewing margin portion from the cloth end of the working cloth is calculated. Also, based on the data read out of the storage means in the same way, a reference position B corresponding to a sewing position of the cloth end of the working cloth is calculated, and the obtained data A, B are stored as sewing data in a sewing data storage means. A cloth end shape of the working cloth is read by an external form line reading means and stored.

摘要： PURPOSE:To detect the location of a cloth end speedily by a method wherein when the existence of a cloth is detected by a detector for reference, a detecting motion is advanced in the opposite direction to the cloth, and the detection is advanced to the cloth side when no existence of the cloth is detected, and the location at which the detecting result changes is taken as the cloth end. CONSTITUTION:Regarding an upper cloth UW, 10 sets of light emitting elements OSU1-OSU10 and light receptor elements ISU1-ISU10 cast detecting lights which are a dot line form crossing with the end of the upper cloth UW, from the leading end sides of locations A1-A10 of reference optical fiber number, which are previously set, and the location of the cloth end of the upper cloth UW is detected by the reflected lights, and the light emitting elements OSU1-OSU10 and light receptor elements ISU1-ISU10 are operaed one by one in order. Then, when the existence of a cloth is detected, the detecting motion is advanced in the opposite direction to the cloth, and when no existence of a cloth is detected, the detecting motion is advanced to the cloth side. By this method, the location of a cloth end can be most efficiently and quickly researched.

摘要： PURPOSE:To eliminate surely the deviation of a work cloth from a needle location point. CONSTITUTION:While a light receiving roller element at the outside detects whether a pair of upper and lower rollers 17, 28 can sandwich a work cloth, a light receiving roller element at the inside detects whether or not the work cloth is fed in the cloth feeding direction F and makes contact with a roller supporting portion. On the basis of these results of detection, a second unit holds the work cloth in place of a first unit and then the deviation of the work cloth from a needle location point is eliminated on the basis of the result of detection by a cloth end detecting sensor 11.

摘要： PURPOSE:To enable attractive profile sewing by changeably setting a reference position corresponding to the present sewing position according to the progress of sewing process and shifting a cloth end to cancel a deflection amount of cloth end position of a work cloth obtained on the basis of the changed reference position and the cloth end position. CONSTITUTION:A cloth end controller in an induxtrial final sewing machine is provided with a cloth receiving plate driving device and upper cloth shifting device provided between a bed part and arm part, a lower cloth shifting device provided on the lower side of the bed part, etc. A deflection amount of a work cloth end detected by a cloth end detecting means placed at the cloth feed side upstream of a sewing needle from the reference position is calculated by a deflection amount calculating means to shift the cloth end in the direction orthogonal to the cloth feeding direction according to the result of calculation. Then, a reference position data storing means previously storing the reference position data corresponding to the sewing position for the work cloth is provided to changeably set the reference position on the basis of the stored data and the present sewing position data detected by a sewing position detecting means.

摘要： PURPOSE:To provide a lateral feeder of a work cloth which can surely pinch and laterally feed a work cloth on the upper surface of a bed to facilitate a bobbin exchanging operation. CONSTITUTION:When a lower cloth feeding roller 87 in a sewing operation is changed over to an upper sewing position to be exposed to the upper surface of a bed through a bobbin taking-out port 77a below the bed, a shell cloth is pressed with a cloth receiving plate 32 and lower cloth feeding roller 87. The lower cloth feeding roller 87 is rotatably driven to shift the shell cloth in the direction orthogonal to the direction of feeding the shell cloth. Also, when the sewing operation is stopped and the lower cloth feeding roller 87 is changed over to a lower shelter position below a bobbin taking-out port 77a, nothing to hinder a bobbin exchanging operation is in the bobbin taking-out port 77a so that the bobbin exchanging operation can easily be carried out.

摘要： PROBLEM TO BE SOLVED: To prevent a printed edition cartridge from being used in substance without increasing the storage space of a cartridge, and while sufficiently securing durability and making cost low. SOLUTION: The cartridge 18 for housing consumables is provided with a specified rugged pattern shape PT, and a logo mark is used as the pattern shape PT. Furthermore, an output equipment main body 20 is provided with detection switches 22a and 22b for discriminating the pattern shape PT. The detecting position of the switches 22a and 22b is set to an optional position in the pattern PT. By changing the detecting position in every production lot of the output equipment, the inadvertent use of the unauthorized cartridge (pirated edition cartridge) is effectively prevented.

摘要： PURPOSE:To reduce time-consuming jobs required to perform a lot of experiments and calculations and to store results in those experiments and calculations by a method wherein the center point of a circle which passes through a specified number of points relating to the edge of a fabric to be processed or sewing margin and the edge of the fabric is controlled based on the relative positions of the center point and the set position. CONSTITUTION:An upper fabric detecting mechanism 10 has an upper fabric sensor mounting block 14 which is arranged on the upper side of a fabric receiving plate 12 and a fabric edge detecting sensor 16 which is accommodated in a sensor housing 14a formed at the left edge of the upper fabric sensor mounting block 14. Detecting lights are projected in a dot line intersecting the edge of an upper fabric UW from the tips of optical fibers A1-A10 through a first prism 20a and second prism 22a to detect the position of the edge of the upper fabric UW by the reflecting lights. Then, the center point of a circle which passes through three points relating to the detected edge of the fabric is obtained, and relative position of the center point and a set position in the fabric feeding direction is calculated. A fabric feeding device is controlled based on the relative position of the center point and the set position so as to make the sewing margin uniform.
