摘要： An adaptive semiautomatic sewing system (10) comprises a sewing machine (12), a drive unit (42) including a variable speed motor and encoder for counting stitches sewn and for sensing the rotation of the motor, at least one material edge sensor (40) mounted ahead of the needle (22) of the sewing machine, and a microprocessor controller (51) coupled to the sewing machine controls. The system (10) has manual, teach and auto modes of operation. In the teach mode, control parameters for each seam are stored as the operator sews the initial piece. Accurate control of seam lengths and end points is achieved by initiating countdown of a variable number of final stitches responsive to detection of the material edges by the sensors (40). In dependence upon the amount of the stitch which has been sewn upon edge detection, the reverse lever (17) is moved against stop member (13) in order to reduce the length of the last stitch sewn in order to improve the accuracy of the seam end point.

Accurate control of seam lengths and end points is achieved by initiating countdown of a variable number of final stitches responsive to detection of the material edges by the sensors (40). In one embodiment, a window is set up around the stitch count at which terminal countdown initiates to avoid spurious signals. In another embodiment, momentary toggles of the sensors (40) are ignored so that an even wider range of sizes can be sewn with the same taught program.

摘要： A semiautomatic sewing system (10) comprises a sewing machine (12), a drive unit (42) including a variable speed motor and encoder for counting stitches sewn, material edge sensors (40) mounted in spaced relationship in front of the needle (22) of the sewing machine, and a microprocessor controller (51) coupled to the sewing machine controls. Accurate control of seam lengths and end points is achieved by initiating countdown of a variable preprogrammed number of final stitches responsive to material edges detected by the sensors (40) only when the stitch count falls within a predetermined window of values so that inaccuracies from stitch counting are limited to a small portion of the overall seam length. If the sensors (40) do not detect a material edge within the window of stitch values, the sewing system (10) reverts to pure stitch counting to determine seam length.

摘要： A semi-automatic split needle bar sewing machine (10) includes a sewing machine (12) which is driven by a motor (26) that drives a left needle (22) and a right needle (23). A presser foot (24) is operated by presser lift actuator (30). The needles (22) and (23) can activate in unison or independently by use of fall out actuators (41) and (43), respectively. A control chassis (50) includes a microprocessor controller (51) that is programmable through an input panel (44). An edge detector (40) detects the edge of the material to provide feedback for the microprocessor controller (51). The microprocessor controller (51) is operable to sew a decorative pattern with mitered corners by sensing the pivot point of the mitered corner and automatically disengaging one of the needles (22) or (23). The microprocessor controller (51) then continues single needle sewing around the apex of the mitered corner by counting a predetermined number of stitches and varying the length of the stitches such that the needle is in the correct position when the single needle sewing again arrives at the pivot point on the other side of the mitered corner. In this manner, it is not necessary for the operator to manually adjust the length of the stitches around the apex of the mitered corner.

摘要： The present invention includes a sewing machine (12) with a variable top feed mechanism (25) that feeds the top layer of material for a sleeve at a variable rate to change the fullness thereof. The machine (12) is driven by a motor (42) which is controlled by a controller (51). A program is taught to the controller (51) for storage therein. The controller (51) then controls both the motor (42) and a controller (45) for the top feed mechanism to regulate the number of stitches and the relative rates of speed for the top and bottom materials fed by the machine. The program initially is taught to the machine and can be utilized for any type of material or size by inputting the correct sizes and types of material on a control panel (44). The machine (12) therefore semi-automatically sews sleeves onto armholes with the correct fullness sewn therein.

摘要： A compact plotter is disclosed, having a small area in which a plurality of print heads (10) are laterally scanned to print impressions on the paper (14), and the paper (14) is incrementally advanced by an indexer (42) past the print heads (10). A paper travel encoder (36) measures the paper advancement. A computer 22 and a processor 26 are provided to coordinate the printing of pattern data stored in a data base (24) both with the movement of the print heads (10) and the advancement of the paper (14). The computer (22) allocates data from the data base (24) to be printed according to the amount of paper advancement. If the paper (14) is advanced more than a predefined amount, more data is allocated for printing than is actually printed. If the paper (14) is advanced less than the predefined amount, less data is allocated to be printed than is actually printed.

摘要： A cutting system for slab goods is disclosed. The system has three stations operating under computer interface control. In a first station, slab goods, such as synthetic shoe bottom materials and the like, are sequentially loaded for purposes of measurement. At the measuring station, the material is loaded on a slab-by-slab basis, and for each slab of material, a series of measurements are made to determine the largest permissible rectangle for that irregular piece of material. The dimensions are fed to a marker-making system, which, in real time, determines the average of usable material taken from the measurements of all the stacked slabs. A cutting marker is then generated by the marker-making system. The slabs are then moved into the cutting area, utilizing a belt drive upon which the slabs rest in the measurement station. Cutting commences at the cutting station, utilizing a cutting tool mounted on a carriage which traverses that station. A variable hold-down system accommodates different size slabs. When the cutting is complete, material is transported to an off-load station where the cut parts are removed from the system. Flowthrough is achieved by having three discrete stations working independently such that, for example, while measuring is taking place at the measure station, cutting may simultaneously occur at the cutting station and prior cut goods being off-loaded at an off-load station. Additionally, multiple cutting systems may be controlled by a single marker-making system.
